Constant Voltage Transformer (CVT)
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.
