Sanjay marketing supplies constant voltage transformer [cvt]. It operates on the phenomenon of ferro-resonance, ie, on the principle of magnetic core saturation. When non-linear [saturated] magnetic reactance is connected in series with linear capacitance and resistance, ferro-resonance occurs. This unit is ideally suitedfor applications with computers, photocopiers, word processors, printers, etc. It corrects the output in 30 to 40 millisecondsand provides clear voltage free of spikes, surges and transients. It is full proof against overvoltage, overloading and short circuit. A major advantage of this cvt is the accuracy in output voltage regulation. It normally offers 3% regulation and can easily be made better. It does not have hunting or voltage swing. Since there are no moving parts or relays or electronic circuit, it is maintenance free .
