Variable Autotransformer

We “Purevolt Products Pvt Ltd” are a reputed manufacturer and exporter of Variable Auto Transformer or Variacs also popurlay known as dimmerstat.

Variable Transformer made by purevolt are basically and AC power Supplies and they are most popular because they are light weight, cost effective and smaller in size. These Variacs can used for a wide variety of applications and usages. Purevolt regularly export these dimmerstats to lot of companies who are in the field of motor rewinding and testing of industrial electrical motors. The variable Transformers are available in both 1 Phase and 3 Phase. We also have a option to customize these variacs fully as per customer requirements and specifications. Purevolt also supplies these Variacs in both AC and DC Current and Voltages.

Purevolt manufactures and export these variacs in standard sizes which are determined by the voltage and current ratings such as 2 amp, 4 amp, 8 amp, 15 amp, 28 amp, 40 amp, 50 amp, 60 amp, 75 amp, 100 amp, 150 amp and 200 Amps and voltages of Input 240 / 270 Volts for 1 Phase with taps at 0-30-240-270 voltages so that for 3 Phase operations, 3 single Phase unit can be connected in Star so as to provide for 470 Volts phase to phase connection facility.

The above range of Variable Auto Transformer is made in both Air Cooled Variacs and Oil Cooled Dimmerstat. As explained above we are capable to fully customize these variacs as per customer needs and applications.Some of the popular applications for these products are as under :

  • Control of A.C. voltage in Research , testing and development work.
  • High voltage and Low voltage tests.
  • Voltage control for meter calibration, phase-angle control in the calibration of wattmeters and power-factor meters.
