Servo Controlled Voltage Stabilizer Transformer

Servo Controlled Voltage Stabilizer Transformer


Certification CE Certified
Automatic Grade Automatic
Features Auto Cut, Easy Operate, Stable Performance
Warranty 1 year
Motor Capacity 7.5 H.p
Voltage 390/400 volts


  • Easy installation
  • Easy operations
  • Low energy consumption
  • High tensile strength


The electrical motors can be affected by higher current (particularly smaller capacity motors upto 7.5 H.P.) in three ways:

  • Higher current produces higher losses and thereby premature failure of winding
  • Higher losses of electric motors also increase the losses of cables, switches and transformers
  • For smooth continuous operation of motors, over load relays are usually set at 20% higher setting


Other information:

  • These controlled voltage stabilizers are maintained at 390/400 volts, the motor will operate smoothly drawing 15 - 20% lesser current and correspondingly the relay setting can be reduced by 15 - 20%
  • In case single phasing occurs, the relay will trip in 40-50 seconds
  • The motor can withstand the high current
  • Also, the relays, contactors, switch gears incorporated with the motor will be safe
