Product Details

Servo – Controlled Automatic AC Voltage Stabilizers of ‘AE’ make are of ‘Electro – Mechanical (EMS) type. The purpose of voltage stabilizer is to receive a fluctuating AC voltage of large amplitude & deliver an almost constant voltage, which remains within a very narrow band (± 1%) of the nominal voltage – quality of the AC voltage remains unchanged. The voltage variations, which have become a common phenomenon in current power supply system, cause havoc in modern complicated & sophisticated equipments. The voltage stabilizers are meant to take care of this problem & protect the equipments. They ensure longer life of the equipments & also drastically cut down electricity consumption of equipments leading to continuous reduction in electricity bills. Thus, they play an important role in energy conservation which is need of the day.

The EMS type AC voltage stabilizer basically comprises of the following –

  • Dimmerstat (Continuously variable voltage auto transformer).
  • Buck – Boost Transformer (Optional upto 5kVA 1Ph / 15kVA 3Ph).
  • AC Step-synchronous motor.
  • Solid state electronic control circuit.
  • Two switching triacs.
  • MOVs for surge suppression.

Features :

  • Waveform distortion – nil.
  • 98 – 99% efficiency (achieved by optimum design & by use of imported hi-quality CRGO laminations & copper of 99.9% purity).
  • Speed of correction up to 70V/sec.
  • Response time – less than 20 m/sec.
  • Immune to load PF & supply frequency variations.
  • Power loss 2% max.
  • Duty cycle continuous.
  • Life expectancy – 20 – 25 years.
  • Easy & simple maintenance (with plug-in PCBs).
  • Protections – over voltage / under voltage / overload / single phasing    (optional).
  • Very high reliability.
  • Considerable short time overload capacity.
  • Output voltage setting (by potentiometer in Auto Mode & by ‘Raise’ / ‘Lower’ Push Button in Manual Mode).
  • Operation – Auto or Manual.
  • LED Indications for Input Voltage ‘High’ / ‘Low’.
  • Metering (Analogue or Digital) – AC voltmeter with / without selector switch.
  • Non-standard requirements can be catered to, such as AC Ammeter, Frequency Meter, PhaseSequence Meter, Single Phasing Preventer, Stabilizer by-pass arrangement, etc.
