The ferroresonant transformers, which are also known as Constant Voltage Transformers (CVTs) or ferros, are also good surge suppressors, as they provide high isolation and inherent short-circuit protection.
We manufacture Constant Voltage transformer or CVT which use 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 ferroresonant approach is attractive due to its lack of active components, relying on the square loop saturation characteristics of the tank circuit to absorb variations in average input voltage.

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.
