Exploring Common UPS Configurations for Reliable Backup 

Power fluctuations can pose significant dangers to your electronic devices and computer in the modern world. To protect against these fluctuations and avoid potential damage, backup power supplies, also known as UPSs, are constructed to stabilise the power supply. Different UPS designs offer varying degrees of protection against disturbances such as power surges, noise interference, overvoltage, undervoltage, power decline, and power outages.

Manufacturers have devised a variety of UPS systems, including line-interactive, double/online conversion, and offline/standby configurations, to address these issues. This discussion will concentrate on online and line-interactive UPS layouts, comparing and contrasting them to assist you in selecting the optimal solution for your specific requirements. First, we'll discuss online and line-interactive UPS here.

Line-interactive UPS

A line-interactive UPS maintains the inverter's connection to the electrical grid. In the event of a power disruption, it switches the DC route from the battery through its normal charging mode to its emergency power supply mode. This ingenious setup permanently links the UPS's output to the battery-powered AC inverter. The UPS inverter goes into battery charging mode when the source of input for AC power is stable. When the mains supply goes out, the UPS's transfer switch opens, allowing the battery to provide the device's output. Since an inverter is always wired to the output, it provides additional filtering and results in fewer switching transients.

Pros of a line-interactive UPS include:

  • High dependability
  • Reasonable voltage conditioning
  • Fewer parts
  • Sturdy build
  • High efficiency
  • Less power usage

Negative features are:

  • Unreliable above 5KVA
  • No safety against kinds of power fluctuations
  • Reliance on batteries is necessary for high-voltage distortion zones
  • No frequency regulation or power factor correction

Double/online conversion UPS 

A double-conversion UPS, as the name suggests, does two power conversions: The primary source's Alternating Current (AC) is converted into Direct Current (DC) and stabilized before being supplied into an inverter, which turns the DC back into Alternating Current (AC). In the event of a mains power failure, the UPS will switch to battery power without human intervention. Since the inverter has already been activated, power is transferred to the battery instantly. The double-conversion process reduces power disturbances from the mains, such as harmonics and waveform distortions. Thus, online UPSs offer the highest level of safety for IT hardware.

The advantages of a double/online UPS are:

  • More precise voltage management
  • No interruptions in service
  • Time required to convert direct current to alternating current is minimal
  • Voltage quality is stable if there are no spikes or dips
  • Distortion-free load voltage
  • Highest possible safety from power fluctuations
  • Near-perfect electrical output

The cons include:

  • A huge heat sink for complex designs
  • More power dissipation
  • Reduced UPS efficiency as the inverter is constantly running
  • Increased wattage of the rectifier as it has to power the inverter and the battery charger
  • More expensive than similar UPS options

Comparing Line-Interactive & Double/Online UPSs for Power Backup 

All varieties of UPS systems were created to safeguard hardware and electronic devices in the event of an unanticipated power outage. However, their true potential varies because of differences in their underlying operating principles. Online and line-interactive UPS, provide the same level of protection but in different ways:

Noise/surge filtering

To protect electronics from being harmed by lightning, electromagnetic (EMI/RFI) line noise, and power surges, all UPS systems have surge suppression and line noise filtering features. In particular, the double-conversion functioning of the online UPS unit provides enhanced protection by isolating equipment from facing issues with the alternating current.

Voltage regulation 

Line-interactive UPS can automatically regulate voltage if it falls outside of predetermined ranges. An online UPS achieves greater precision in voltage regulation due to its double-conversion process.

Time required for battery transfer

To ensure the uninterrupted operation of even the most power-sensitive devices, line-interactive UPS systems make the transition to battery power in 2 to 4 milliseconds. Since the inverter will already be powering the linked equipment load in the event of a power failure, there is no transfer time with an online UPS system.

All About the Application of Line-interactive & Double/Online UPS 

Departmental servers, households, SMBs, and MSMEs can all benefit from a line-interactive UPS that provides the high-power reliability they require. These devices use a unique set of operating principles and can be widely used in set-ups ranging from private residences to massive data centers. They require charging the battery either once or twice a day. But, they may require frequent charging in places with poor infrastructure where the alternating current line is unstable, varies dramatically, or is greatly distorted.

The best online UPS system isn't just useful in industries like computing, transportation, securities, banking, medicine, and communications where continuous power is required; it's also the go-to option for providing backup power to essential equipment and servers in data centers. They are particularly used in intensive care units that have very important life-saving medical equipment.

The bottomline

Different types of UPS solutions offer varying degrees of security, so knowing which one you're using is crucial. Because of their fundamentally different designs, online and line-interactive UPS offer different features, functions, benefits, and limits. Furthermore, a UPS's internal architecture affects its performance in a variety of contexts.

The Beginner’s Guide to UPS Systems

Uninterruptible Power Supply Systems (UPS Systems) perform backup and conditioning roles for the systems they are connected to. They are very important in situations where primary power supplies fail or other power supply problems, such as spikes, brownouts, electrical noise, sags, or surges. UPS systems protect small business applications used for communication, entertainment, or security from electrical surges or sags and prevent business disruption, data loss, or even injuries and fatalities.

In this article, we’ll tell you all about UPS Systems and have you choose the best UPS type suited to your business.

Understanding UPS Systems

The UPS is a battery backup system that can perform many important functions in a set-up that depends on a primary power supply. Its main role is to act as a secondary power supply that will run long enough to shut systems down properly and back up data sufficiently when an unexpected power outage occurs. The UPS also performs an important surge-protector function to keep devices safe from the harmful effects of abnormal voltages and surges, including reduced performance or lifespan of the device. So it saves the company a world of pain when it prevents data loss and device stress or damage by preventing forced shutdown during an unforeseen power outage.

An acid or lead battery inside the UPS system provides the backup power required when its sensors detect that the main power supply has suddenly shut down. This backup power will not be available for an extended period, but it allows operators to save or back up any critical data and shut the system down gradually or function until the power supply is back on.

Types of UPS Systems

UPS Systems are of three main types - the line interactive system, the standby system, and the online system. Other types exist, but they are usually hybrid combinations of two or multiple main UPS system types.

Let’s discuss these system types in more detail:

1. The Line Interactive UPS System

This system serves a dual purpose as a backup power source and a power conditioner. It is the optimum system type if your devices function in an environment with rare power outages but frequent fluctuations. The system can adeptly handle several ranges of fluctuation episodes before switching on its battery power backup. This benefit of handling wide ranges of fluctuations and the circuitry for voltage boosting is a critical one. In fact, wider ranges of accepted fluctuation in the system will give you more overall protection for your devices.

2. The Standby UPS System

The Standby system earned its name from its basic function of acting as a standby when there is a sudden power outage. It performs conditioning for minor surges and usually draws power from the main AC source during normal functioning. The system is also provided with an AC/DC inverter that kicks in when sensors detect trouble in the main power source. But this system has a small transfer time drawback that users should be aware of.

3. The Online UPS System

The online UPS system, also called the double conversion system, performs by isolating the device load from the main power grid. It achieves this by following an AC/DC DC/AC double switch. The online UPS system converts the incoming supply of main power to DC and then back to AC, effectively isolating the load from the rest of the grid.

This switching function is possible because of the rectifier device in the system, which receives incoming power, converts it to DC, and feeds it into the inbuilt battery and onto the connected device through an inverter. This system nullifies the need for power transfer switches. In a power outage, the rectifier drops its connection with the main grid and uses the battery energy to power the connected device until the main power is restored.

How to Choose the Perfect UPS System for your Needs

Four main factors should determine your choice of UPS systems for your devices. These are discussed at length below:

1. Determine common power problems.

Power blackouts are the most common power problems people are aware of. But when electronic devices and critical equipment are involved, you will need to be aware of the following:

  • Blackouts - Power outages lasting anywhere from a few minutes or seconds to a few days.
  • Surges - A brief, intense burst of electric energy when there is lightning– it affects the main power supply.
  • Voltage sags or over voltage - Fluctuations in voltage that are not as intense as brownouts or surges. Voltage sag is a brief, small drop in voltage, while an overvoltage is a voltage spike.
  • Brownouts - A drop in voltage for a long duration that could have been intentional, uncontrolled, or accidental.
  • Frequency noise or variations - These are abnormalities in the main power supply. Frequency noise, or line noise, are abnormalities in the primary power source that cause disruptions in the power circuit. Frequency variations are usually caused where generators are in use, and the occurrence of power fluctuation is more frequent than normal.
  • Harmonic distortions - This is an anomaly in the primary power source when it gives out an unusual electrical signal.

If your business is operating in an area that faces blackouts, brownouts and surges but none of the other power anomalies, a standby UPS system could work well for you. An online UPS system may be required if you face a combination of all the above power problems.

2. Select the right size.

The optimal UPS system for your business will have to be sized correctly in terms of capacity. Depending on how much equipment will need the supported power supply and the combined load or amount of power they will use, you can choose a UPS with a comparable load capacity. You can find information about capacity and load in the corresponding user manuals of your devices and the UPS system you are considering. Manufacturers or other professionals could also help you make the right connections to match device load to UPS capacity.

3. Determine optimum run time.

Runtime is the next important consideration for choosing the right UPS system. Runtime is the amount of performance time your system requires to provide alternate power when there is a power outage or other trouble in the main supply. Calculate how much time you will need to perform a safe system shutdown and data backup, and this can be used as runtime. System load or the amount of power load your system needs to back up has an effect on runtime. A larger load will mean less runtime or battery life, and vice versa.

Think in ranges when determining optimum runtime. Work from the least amount of time you will need to optimise your devices and work up from there. A broader range of runtime will give you more choice in UPS systems.

4. Choosing an appropriate form factor.

There are three main form factors or size and shape of the device housing. These are:

  • Rack-mount systems - meant for server rooms.
  • Desktop systems which are compact - can fit under desks and are discreet.
  • Mini-tower or tower-style systems - are aesthetically pleasing and can be displayed on desks.

In short, form factor choice is usually determined by where you want to place your system.


UPS systems are not everyday buys. They are high-priced investments that must be carefully considered and matched to your needs.

Safety First


Electrical systems form a crucial part of every organization that runs on electrical devices. If there is even a little problem in the system, it shuts down, and the movement of work in the organization comes to a standstill. This is where power quality audits come into the picture. They act like bulletproof jackets for the electrical system. It checks the safety and efficiency of an organization's electrical system.

How does PQA work?

It works in the following ways :

  • Checks the quality of voltage- it maintains the network's frequency, thereby ensuring that there are no high or low-frequency disturbances present in the network that may be capable of damaging components of the system.
  • Checks the continuity of power supply - it ensures that the power is constantly available in the network. All the connected devices are operating consistently without any hurdles, and that the efficiency of not a single appliance has been compromised.

Importance of PQA :

  • Provides a wholesome picture of the electrical system's state and its operational statistics at any point in time.
  • Analyzes variations in voltage, flickers, frequency variations, harmonics, etc.
  • Ensures the devices' good performance connected to the electrical system by providing enough voltage and deterring any fluctuations.
  • Develops schedules for maintenance of the power system.
  • Assessment of the sensitivity of all equipments and disturbances of any data caused to the equipment, can be prevented well in time.
  • Identify the source of the event and the frequency of events.
  • Helps by monitoring the conditions of the electrical system.
  • Helps in the evaluation of performances against various specifications.
  • Assists in predictive maintenance.
  • It identifies the exact location so that the specific source is recognized and the problem is resolved.
  • Identify the precise timing of events.
  • Gives a precise report that helps in preventive maintenance to know all the measures that need to be taken promptly in case of disturbances.
  • It improves the power quality and brings in efficacy.

Consequences of bad power quality can inflict serious losses to your company in case there is a disruption in the flow of a sinusoidal wave of power supply, which could cause significant damage to your electrical system, in turn affecting the supply to your devices. By this, not only are your devices getting damaged, but there is also a breach in the working momentum among your employees. This will further reflect the progress of your firm. A power quality audit can enable you to maintain good power quality and, in this way, discourage any hindrance that comes in the way of your company's prosperity.

To summarise, one can say that a power quality audit determines how fit your electrical system is. Moreover, it acts as a warning system and helps stave off any electrical issues, thereby protecting your power system and the appliances connected to it. Nantech Power Systems Pvt Ltd is one such company based in Chennai that provides you with top-notch Power quality audits.

The UPS Rental Checklist

It is annoying when essential data is lost simply because of an unexpected power cut. The frustration and not to mention the potential loss of work and efforts can spoil anybody’s mood. Power cuts hamper not only digital data but may as well damage factory goods if the energy supply stopped abruptly. Thankfully, the invention of inverters helped us restart our power and avoid grim situations, but another device went another step further! The UPS that stands for Uninterrupted Power Supply, trumps the inverter by its ability to back up the power supply so rapidly that there was virtually no interruption.

The UPS is an essential device, that also serves to protect other devices from the adverse effects of power fluctuation and power cuts. It is essentially a back-up current supply in the instance of the failure of the primary power source. It is not used for heavy factory equipment and is primarily used for computers. Unless, your locality, office, or residence faces frequent power cuts, we at Nantech recommend that you rent a UPS and not buy one. Since Chennai has a booming IT industry, and many more investments in the IT sector are predicted to come their way, Chennaites should consider investing in renting a UPS.

There are some indications for renting a UPS:

Budget: If you are short on budget, renting a UPS will cut down on installation fees!

Nomadic work environment:
If you travel frequently for work or otherwise and do not want to test the power system at a new location, it is advisable to rent a UPS instead of carrying the bulky device everywhere you go.

Things to be kept in mind while renting a UPS are as follows:

Rental Clause:-
Always read the rental agreement provided by the UPS provider carefully. Consider factors like monthly rent and service policies and run a cost-benefit analysis before making a decision. Rental duration should be given a lot of thought as it will also it will also impact the number of service appointments.

Battery status:- You should receive a new battery with every UPS rental. Make sure the battery works and get it installed by a professional.

Type of UPS needed:
Depending on use, choose any of the three most common systems.

  • Stand-by UPS:-

It is best for home use, supplying light equipment like computers and such.

  • Offline UPS: -

It is best for shops and intermediate level commercial use.

  • Online UPS: -

This is the most efficient and advanced model, suitable for industry and factory-grade equipment.

Rent a UPS that will require less maintenance. The provider in standard practice, along with the UPS also provides maintenance services which can be scheduled at the convenience of the consumer. Servicing charges are nominal unless new parts need to be added or replaced.

Safety and Technical Compliance:
Any device when purchased or rented should meet standard safety guidelines, and the UPS system, irrespective of type, is not exempted from this rule. Remember to read the instruction manual, and understand that it is your right to ask for a copy of the warranty certificate of the device. Try to rent a user-friendly system that will not take much skill or knowledge to attach to other equipment.

We at Nantech provide UPS supply and comprehensive customer service, feel free to revert to us in case of any query or doubts regarding the UPS systems.

Why is UPS Maintenance Important?

It is obvious that all electrical gadgets should be properly maintained for a system's smooth functioning. Since all major businesses rely upon their power supply, the UPS must be maintained to save both time and money. The following reasons enunciate the importance of UPS maintenance for the safety of the machine.

Saving Data

During a power failure, all the important data stored suffers a series of setbacks as the most personal data is disrupted at this time. Immediate switch- over from UPS's mains if the power failure is possible only if the UPS is well maintained. Hence the data saved will remain without loss if timely UPS services are done.

Enhancing UPS Efficiency

When the surveyors visit to check the equipment, we need to ensure that the instrument's capacitor can moderately regulate the temperature process. It is always better to keep the UPS in a dry place where there is uniformity in temperature to strengthen the overall process. The customer should check all major components of the system before the maintenance visit to ensure that all repairs of the equipment are carried out properly.

Utilizing The Services Of An Appropriate Maintenance Contract

The maintenance contract should do regular visits by following a stipulated schedule for the system's proper functioning. Instantaneous response from Nantech services limited during an emergency makes them reliable and trustworthy throughout the installation process.

Monitoring The Battery Functioning

Frequent testing of the voltage and keeping track of the battery will help the customer to be aware of replacing the batteries whenever it is required during the maintenance visit. The impedance testing will be beneficial in predicting the duration and reliability of the battery. Chennai based company has the edge over the others as it designs new batteries for the power system and provides all the essential technical support.

Delivering Parts For Proper Efficiency

For the clients' benefits, a wide variety of spare parts are provided whenever an emergency pops up. Cooling systems, air filters, and all stocking parts of the engine will be implemented without fail, and frequent monitoring enhances the durability and credibility of the Chennai-based company. If the technicians do not properly investigate, there is a high chance of failure in maintaining a UPS system. Individual unique testing of all parts is recommended for the smooth running of the system.

To put it in a nutshell, only trained personnel should be appointed to rectify the UPS system. Maximum service life is totally dependent on the level of maintenance of the system. Every month there should be a visual inspection for checking the damage of batteries. The place where the UPS is installed should be completely free of dust particles to prevent unnecessary damage. Measuring the voltage of each cell guarantees the longevity of the equipment. A smooth working atmosphere without any data loss can be systematically provided by increasing the UPS's working life.

Why Online UPS Systems Are The Future

An Uninterrupted Power Supply (UPS) system is an emergency power system that provides backup power for your connections when the main power supply line fails to deliver or the voltage levels drop below a certain threshold. During Power Cuts, A UPS system comes in very handy as it not only supplies three-phase power to your equipment but it also protects it from supply line noise, surges, and voltage EMFs.

Earlier systems

We still use these systems for backup power supply, but now that Online UPS systems are the future, we should discuss them first.

Offline UPS system

In the earlier days of UPS systems, most of Chennai used offline systems. These systems worked by basically providing backup power to the load only when the mainline failed. These systems directly give raw mains to the connections and a connected battery in parallel to the supply line. Link to the mainline ensures constant power supply to the battery for charging, and in a power failure, or if voltage levels drop, then battery power is switched on.
The drawback is that since it connects directly to the main power supply line, it provides little surge protection, which can damage your electronics. The other liability is that since the battery supply has to go through an inverter and then to your equipment, there is a time delay of around 10ms for power delivery and little to no voltage regulation. It isn’t a reliable system overall.

Line-Interactive System

Line Interactive UPS from NantechThese systems are a slight improvement over offline UPS systems. Line-Interactive Systems work by supplying power to the inverter, which then has a bypass line that sends DC to a connected battery. The supply line also connects to the main switch. When a power failure occurs, or a voltage drop occurs, the transfer switch closes, and we lose connection to the mainline. The battery then starts supplying DC power to the inverter, which converts to AC and supplies to your connections.
The problem is that even though they protect your equipment better, it doesn't offer complete protection from surges. It has a power delivery time delay of around 5ms and voltage regulation of ±8-15% within nominal voltage values. It is an improvement, but compared to Online systems, it is still lacking.

Online Systems

These are the latest in the UPS systems! The improvement over Offline and Line-Interactive Systems is significant. They use a 'double-conversion' system. A Rectifier connected to the main supply passes DC to the inverter supplying AC, and a battery connected in parallel to this line along with a bypass switch. In a power failure, the power switch turns off, there is no power going through the rectifier, and the battery-inverter supply continues.
Thus, there is maximum protection from voltage surges, almost no time delay, and ±2-3% voltage regulation of the nominal values. Other advantages are:

  • No Voltage Fluctuations
  • Load Voltage quality is relatively distortion-free
  • A near-ideal electrical output and protection against all power irregularities

These make Online UPS systems used in many critical areas such as data centers, hospitals, and businesses. Many people are upgrading their existing UPS systems to Online UPS systems!
