SERVO CONTROLLED VOLTAGE STABILIZER

SERVO CONTROLLED VOLTAGE STABILIZER

 

Servo Controlled Voltage Stabilizers Essentially Consists of :
* A continuously variable auto transformer driven by low intertia Servo Motor.
* A Buck Boost Transformers.
* An I.C. based control circuit with electric switching of Servo Motor.

Features :-
* Truly closed loop proportional Servo Controlled System.
* Fully Solid State Control Circuit.
* + 1% Regulation.
* Zero Wave from Distortion.
* Negligible losses - high efficiency 95%
* No Phase shift-No effect of load power factor.
* Works over wide input frequency range.
* High speed correction from 20V / per second to 35V / per second.
* Input supply very high-very low indicators.

Optional Features :-
* Output over voltage & output under voltage trip facility with visual indicator and or audible alarm.
* Electronically controlled output over load trip facility with visual indictor and or audible alarm.
* Output voltage regulation adjustability from 0.5% to 1%
* Digital volt meter and Ammeter. 
* Single phasing preventor (for 3PH )
* Built in spike suppressor.
* 3 PH Stabilizer available for balance or unbalanced load.
* M.C.B. on Input and / or Output side.
