Servo Stabilizers

Servo Micro Processor

We bring forth high efficiency Servo Micro Processors for single phase as well as three phase applications. Our servo stabilizers are exclusively and precisely designed to protect various costly electric equipments from harm caused during high/low voltage fluctuations and provides them optimum performance. Servo stabilizers are used in Air Conditioning Plants, medical Equipments, Mall & Commercial Complex, Escalators & Elevators, Pharmaceutical Industries and more. Its sturdy construction and sleek design has made it the most demanding stabilizer in the market.

ADVANTAGES OF SERVO STABILIZERS :
  • Automatically corrects voltage on regular intervals.
  • When supplied with constant voltage, synchronous motors operate highly efficiently.
  • Protects expensive electrical equipments from menace of voltage fluctuation thus lowers the cost on maintenance.
  • Better efficiency in plant with less production losses.
  • Increased productivity rate.
  • 100% depreciation as per Income Tax Act.
  • Reduces the electricity bills approximately up to 15% (This also depends on the input variation loading and the number of working hours).
  • As the generator is not required to run at High/Low input voltage thus it saves on diesel cost.
  • The average pay back period of Servo Controlled Voltage Stabilizer owing to its high energy saving capability which is approx. 18 months.

OUTSTANDING FEATURES OF SERVO STABILIZERS :
  • Fast correction rate and very high efficiency.
  • Works over wide input frequency range and no waveform distortion.
  • Specially designed high performance I.C. based control circuit for ultra high reliability.
  • Auto/Manual operation facility.
  • Over voltage and under voltage indicators.
  • Unaffected by load Power Factor.
  • Plug in glass-epoxy control cards designed for easy line service ability.
  • All components used are of reputed makes confirming to relevant IS/BS standards.
  • Easy accessibility from all four sides. Stabilizer are subjected to routine and time tests in accordance with latest IS standards (IS: 9815-94)
