Switched Mode Power Supply [SMPS]-
The SMPS is an electronic power supply that connects a switching regulator to convert electrical power efficiently. The SMPS transfers power supply from a DC or AC source to DC loads, such as a personal computer, while converting voltage and current characteristics.

Automatic Voltage Transformer[AVT]-
The AVT is a stabilizer used for emergency power supply, oil rigs, generator sets and so on. It is an electronic power device used for variable voltage and this can be done without changing the power factor. If the voltage of the power supply is more than required, a step- down transformer is used and if the voltage is less a step-up transformer is used.

Electromechanical Regulator:
The electromechanical regulator is used for regulation of voltage on AC power distribution lines. These stabilizers are also called voltage stabilizers or tap-changers.To select the appropriate tap from an autotransformer these voltage stabilizer use servomechanism operation.

The uses of a stabilizer: A Voltage stabilizer is used to provide a constant current to electrical gadgets and also protects them from damages due to voltage fluctuations. Some of the main uses are:

• In under developing third world countries constant power supply is a problem. This intermittent power supply and voltage fluctuations lead to a vital loss. In such situations, stabilizers come to rescue.
• Slightest variations in AC power supply can cause vital equipment to crash and essential processes to falter. It may also lead to data processing error.
• Huge damage can be caused to the sensitive electronic device due to common mode noise. Dirty mains and interrupted power supply can cause a lot of problems.
• Most of the electronic devices can work on low voltages but sometimes problems like sags, brownouts and surges occur which causes huge problems.
• Spikes are fast short duration electrical transients in voltage, they are typically caused by lightning, power outages,short circuit and malfunction in the power company. Usually, all electronic devices can handle spikes of 100V, but more than that may lead to the crashing of the hardware.

The benefits of CVT over others:

Better voltage regulation: The fluctuation in input voltage is up to 40% the CVT will provide with a better voltage regulation of 1 to 4%.

Current limit: Control on current supply according to the need is the major advantage of CVT. The other stabilizer has a built-in control of constant current supply as against voltage.

Durable: The CVT does not have any movable part so it is easy to maintain and work for a longer duration than other transformers.

Can detect the slight voltage fluctuation and provide a constant voltage supply for the uninterrupted flow of work. Even if there is a small power block, the CVT is able to fill the gap.

The conclusion:

The CVT is one of the best stabilizers in the industry. The reliability and simplicity of the CVT has made it a popular choice. It is a durable device and can be in constant use for a long time without any adverse effects. A CVT is a self-protecting device which protects both its supply and the load connected to it. So to conclude, the Constant Voltage Transformer is the perfect option for any sensitive electronic device which requires a constant power supply.

Power cuts and fluctuations are commonplace in India; these fluctuations can be detrimental to your electrical equipment. To protect them from these fluctuations and to get a voltage that is consistent and safe, a Servo stabilizer is needed. Many products have come up with ads that say their equipment have SMPS and hence there is no need for a stabilizer. These claims are far from the truth, read below to understand why there is a need for voltage stabilizers and how it can protect your appliances.

Why have servo voltage stabilizers:

Some electrical equipment like the X-Ray machines, PH-meter, etc. gets affected when there is a high voltage whereas compressors, refrigerators, etc. get damaged due to low voltage. So it becomes mandatory to select servo voltage stabilizer in Chennai on load as well as voltages that can provide a constant voltage. Electricity boards are also unable to provide clean power as the load is enormous and the number of electrical appliances running at end user is too high. There are single or three phases of electricity in the range of 230V to 415V. The 3 phased connections are divided into three lines each with 230V, so the range of electrical appliance is 220 to 240V. When the voltage is higher or lower than this range, there has to be a correction as the SMPS within the device cannot handle this and hence the appliance can be damaged. When you install a stabilizer got from voltage stabilizer dealers, you can safeguard your electrical equipment.

Advanced technology has transformed healthcare and is critical in diagnosing, monitoring and treating patients who are suffering from illnesses. So technology is playing a significant role in improving the health of people. MRI, X-Ray, and other such imaging technologies are critical for patient care, though these are procedures which do not consume more than few minutes. If there is an electrical outage, it can majorly impact the operations of these facilities. To prevent such disruptions, UPS for medical equipment is to be installed. The Uninterrupted power supply can act as a short time power supply and also be a stop-gap arrangement before the generator kicks in. They are also adept at regulating voltage when the imaging systems are in use so that there are no hiccups while the scan is in progress.

Importance of UPS for medical equipment:

Clean Power: One of the essential need for having a UPS in medical imaging systems is that they are a source of clean power. Clean power is energy that doesn't have variable voltage, and there is no dip or spike. Some areas that are far away from power plants experience these fluctuations more than others. It can also happen when the amount of electrical equipment used in a location is, and thus there is more noise in the current. When medical equipments receive this dirty power, there are chances of it getting damaged or produce lousy quality images. When you are on the lookout for UPS look for ups manufacturing companies that provide clean power. It is also seen that online ups manufacturers have this capability than a standby UPS. The cost of online UPS is high compared to the standby, but if you are located in an area where there are power fluctuations, then it's worth the money.
