CVT (Constant Voltage Transformer)

Home / CVT (Constant Voltage Transformer)

Optimum performance of sophisticated electronic equipment is highly dependent on the stability of the mains voltage. The continuously fluctuating mains supply, transients, spikes & surges produce harmful effects.

‘ABP’ Constant voltage transformer gives effective solutions to all these problems.

Constant voltage transformers are based on Ferro-Resonance Principle & it consists of two basic components i.e. Ferro-Resonant transformer and capacitor.

‘ABP constant voltage transformers’ are ideally suitable for computers & like systems. Data processing equipment, Bio – Medical equipment, Telecommunication equipment. Telex, EPABX, Electronic Typewriter, Fax Machines and any other sophisticated electronic equipment which requires a precise mains supply.

KEY FEATURES


  • High reliability as no semiconductors/moving parts used.
  • Provide relatively sine wave output irrespective of quality of input wave shape.
  • High insulation values.
  • Instantaneous voltage regulation.
  • Output highly isolated from mains for suppression of transients & spikes.
  • Short-term over LOAD capacity.
  • Intrinsic current limiting & short circuit protection.
  • Higher input voltage control range for LOADS less than rated load.

RECOMMENDATIONS

  • Place the CVT away from equipment and all magnetic display and storage devices like diskettes, monitors, tapes etc.
  • It is safer to connect CVT to mains supply through a 3 Pin socket ensuring thereby the availability of proper ‘Earth’ connection.
  • Switch ON the CVT first then the attached peripherals and while switching OFF, switch OFF attached peripherals first and then the CVT.
  • In case of supply from a generator, check frequency, CVT is not be used if frequency variation is beyond 50 +/-1Hz.
  • Switch OFF the CVT when not in use.
  • Not to be used for high inductive LOADS like motors.
