45 Hz To 55 Hz Fully Automatic Servo Voltage Stabilizer With Voltage Limit Indicators

We manufacture and offer premium quality servo voltage stabilizer that are in accordance with ISO standard. Our voltage stabilizer are ideal for protecting electrical and electronic systems from voltage fluctuation. Our stabilizers are designed to provide constant output with tolerance of /-1% which enhances their efficiency.

Principle of Operation
Servo stabilizers are based on the principle of comparing the output voltage with built in stable reference voltage source. The solid state control circuit operates the motor whenever the output voltage falls or rises beyond a preset voltage. The secondary winding of the buck boost transformer is in series with the main supply. The primary winding is connected to the motorized control auto transformer (Variac). Output voltage variation due to any reason makes the motor to move in proper direction, so as to feed the primary of the buck boost transformer a proper voltage which in turn produces voltage in the secondary to keep the output to set level with tolerance of /-1%. Some of the salient features of servo stabilizers include the following:

* Fully automatic solid state glass epoxy plug in control card
* Very low internal impedance
* No effect on load power factor
* High efficiency better than 95%
* High reliability servo motor
* Wide frequency range from 45 Hz to 55 Hz
* No effect by any transient over voltage surges
* Auto-Manual operation
* Voltage limit indicators
