Salient Features :
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.
FIELDS OF APPLICATION : 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.
RECOMMENDATIONS:
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.
