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.
