CVT (Constant Voltage Transformer)

Model : CVT

Price : 0.00

Description :
The AC mains powers 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 storage characteristic in conjuntion with the mains capacitor, and this energy storage produces a self-generated AC flux field which is indirectly excited from the input winding. 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.

SALIENT FEATURES  

  • No semiconductors or moving parts used, hence very high reliability.
  • Intrinsic current limiting and short circuit protection.
  • Output voltage correction within ½ Cycle ( 10 msecs.) from no load to full load for specified load and line variation.
  • Short term over load capability.
  • Energy storage for line loss up to 3 msecs. at typical loads.
  • Higher input voltage control range, for loads less than rated load.
  • Very high line transient/spike rejection capability and excellent input to output isolation characteristics.
