Variable Auto Transformers (Variac)

Variac or variable auto transformer manufactured by Servokon is available with AC control voltage controls that offer continuous AC voltage supply. Variac ensures a distortion free output that is suitable for sensitive electronic appliances and equipments in residential areas and industries. Manufactured with cutting-edge technology, these auto transformers ensure a consistent linear regulation of AC voltage to provide high output and negligible waveform distortion. It is suitable way of controlling current, light, heat and motor speed with a voltage factor. This transformer finds its wide applications in Auditorium, hotels, conference hall, laboratories, College & universities, Welding equipments, Servo stabilizer, rectifiers, battery charger and Testing instruments. Construction of Variable Auto Transformers (Variac)

Construction of Variable Auto Transformers (Variac)

  • There is a single layer winding on toroidal core of high-grade cold rolled grain oriented (CRGO) steel
  • A special durable contact surface is made on one side of the copper winding and a specially finished carbon brush slide smoothly on the surface
  • A contact arm with a carbon brush is fitted on the centre shaft
  • As the control knob is rotated, the carbon brush slides over the winding

Features of Variable Auto Transformers (Variac)

  • Can enhance the output voltage in excess of twice the input voltage
  • Any desired voltage within the maximum range can be obtained by adjusting the carbon brush
  • Calibrated dial show approximately output voltage at no load
  • The contact arm can be moved both manually and by motor
  • Delivers an output voltage from 0 to above line voltage
  • Constructed with 99.9% pure copper
  • High grade CRGO steel is used for constructing coils
  • Low temperature rise
  • Wide assortment of current rating 4 Amp. To 1200 Amp
  • Spare carbon brushes provided up to 28 Amp
  • High quality carbon brush
  • Step-less voltage control
  • Short time overload capacity
  • Maintenance cost

Application of Variable Auto Transformers (Variac)

  • Auditorium, hotels, conference hall, laboratories etc.
  • Servo stabilizer, rectifiers, battery charger
  • Welding equipments
  • Testing instruments
  • College & universities

Servokon Single Phase Variable Auto Transformer

Servokon specializes in manufacturing and supplying high quality automatic voltage stabilizers to meet the requirement of different industries as well as residential units. This stabilizer has a transformer and a power control circuit for controlling output AC voltage. The control circuit controls the voltage or power automatically and regulates it to a level that is set or required. The best part is that in the entire operation, the voltage regulator doesn’t require any manual interruption, it functions automatically. Once it is set, you need not to check the voltage every time the main voltage fluctuates. These power regulators are generally used with the home equipments like refrigerator & air conditioner.

As automatic voltage stabilizers are loaded with plethora of features, they are highly demanded in residential applications for protecting Refrigerator, Deep freezer, Bottle and water coolers, BOD incubators, Air conditioning appliances from voltage fluctuation. We are a quality concerned company that doesn’t compromise with the quality during the manufacturing process and even the final dispatch is done under the supervision of technical experts.

Features of Servokon Single Phase Variable Auto Transformer

  • Servokon Voltage Stabilizers are easy to install and operate
  • Low maintenance required
