Ferro Resonant Transformer ( CVT )

General Technical Specifications of our Ferro Resonant Transformer (CVT)

Input Voltage 180 V – 260 V AC
Line Frequency 50 Hz
Output Voltage 220 – 230 V ± 1%
Output Step Load Response 2 cycles (30 to 40 milliseconds)
Efficiency 90% (approx) under full load conditions
Output Wave Form Sinewave
Wave from Distortion 5% (approx) under full load conditions
Load power Factor 0.75% lag to 0.9% lead
mbient Temperature -10°C to 50°C
Transformer Type Ferro-Resonant
Effect of Frequency 1.6 (approx) change in output voltage for every 1% change in line frequency

Salient Features for CVT :
  • No Semiconductor or moving part used, hence very high reliability.
  • No feed back control used.
  • Intrinsic current limiting and short circuit protection.
  • Energy storage for line loss up to main 3ms at typical load.
  • Short term over load capacity.
  • Higher input voltage control range for load less than rated low.
