VARIABLE AUTO TRANSFORMER DIMMER VARIAC for step less, break less and continuous control of A.C voltage

Variable Auto Transformer, manufactured by Purevolt is the most useful and effective device for step less, break less and continuous control of A.C voltage and therefore, for control of various other parameters, dependent on A.C voltage. It is ideal controlling device for numerous applications in laboratories and in industrial & commercial fields.

The basic Auto Transformer is meant for operation off a nominal voltage of 240 V A.C & can give output voltage anywhere between 0 – 240 V or upto 290 V, by a simple transformer action. Three such Variable Autotransformer when connected electrically in star & mechanically in tandem, became suitable for operations of 415 V 3 Phase A.C. supply & to give output of 0 – 415 V or upto 470 V.



Rating:- 4 AMP to 500 AMP

Type    : Single  / Three Phase


Technical Specifications:

  • Rated for 240V A.C. 50/60Hz. single phase supply and three phase model for 415V A.C. 50/60Hz three phase 4 wire supply.
  • The output voltage can be varied smoothly over two ranges:
  1. Zero to full supply voltage
  2. Zero to approx. 12% higher than the supply voltage
  • Suitable for indoor use a maximum ambient temperature of 45oC

Salient Features:

  • Simple & rugged in construction
  • Good Regulation- Voltage drop on load is low
  • Output voltage variation on no-load and even on load is effortless, smooth, continuous, break less and linearly      Proportional to angular rotation.
  • High Efficiency- No load losses and load losses are low.
  • Negligible waveform and power factor distortion due to simple transformer action.
  • Excellent short time overload capacity
  • Easy for remote operation with the help of motor drive.
  • Wide range of models.
