Constant Voltage Transformer


Pioneers In Ferroresonant Technology

Our Constant Voltage Transformer (CVT) is a ferroresonant technology designed in the form of 1:1 transformers that are excitingly high on their saturation curves, thereby providing an output voltage which is not significantly affected by input voltage variations.

Constant Voltage transformer or CVT uses a tank circuit composed of a high-voltage resonant winding and a capacitor to produce a nearly constant average output with a varying input.

The input winding normally runs at very moderate Flux linkage levels.

The output winding exhibits an intrinsic energy characteristic, and this energy storage operates in conjunction with the mains capacitor to produce self-generated AC flux Field which is indirectly extracted from the input winding.

Our wide range is spread between 500VA and 5kVA.

Constant Voltage Transformer

Nantech CVT is preferred over conventional stabilisers because of the lack of relays that lead to output voltage interruption for a short span of time. CVT offers complete protection from spikes offering a controlled output voltage. Nantech is a renowned CVT Manufacturer and Supplier in the industry backed by a highly competent team of professionals maintaining standard norms during manufacturing and fast installation. Our products come with low maintenance and no moving parts. We offer a warranty on our products and is backed by an efficient service team.
