1 CVT CONSTANT VOLTAGE TRANSFORMER supplies constant voltage even in case of huge fluctuations in input

Constant Voltage Transformer ( CVT )


In PUREVOLT CVT, the AC mains power the input winding, which is widely separated physically from the isolated output winding. The input winding normally runs at very moderate Flux linkage levels. The output winding exhibits an intrinsic energy characteristic and this energy storage operate in conjunction with mains capacitor to produce self-generated AC flux Field which is indirectly extracted from the Input Winding.


All problems related to variation / fluctuation in Voltages are effectively handled because of this principle and a constant voltage output of & ± 1% is given.


The Result:

Instantaneous Voltage regulation. No effect of input Transient and spikes on the output. Sinusoidal output waveform. A perfect answer and remedy for all types of electronic equipment. Our CVT’s have been designed to give you total protection against power related problems and to condition the power to suit the needs of your microprocessor based equipment. It effectively regulates voltage variation, suppresses transients and bridges short interruptions/dips


Rating Available: 150 VA – 10 KVA

Computers, Data Processing equipment, Colour Photography Labs., Bio-medical equipment, PA equipment, Telecommunication, TV, VCD/DVD recorders & players, Teleprinters, Fax machines and all other sensitive electronic devices.



  • Keep magnetic storage and display devices like Diskettes, Spools, Monitors etc. away from the CVT
  • Switch on the CVT before switching ON the attached peripherals and while switching off, switch OFF attached peripherals first and then the CVT
  • Avoid using the CVT for high inductive loads.
  • Check frequency before using the CVT with a generator. Recommended frequency: 50± 1Hz
  • Switch OFF the CVT when not in use.
