Servo Power Controller

OUR SERVO POWER CONTROLLER IS SIMPLY HIGH SPEED ELECTRO-MECHANICAL DEVICE THAT PROVIDES HIGHLY ACCURATE CONSTANT A.C. SUPPLY & PROTECT AGAINST HAZARDOUS POWER CONDITION. THESE SERVO POWER CONTROLLER IS HIGHLY SUITABLE FOR COMPUTER, XEROX MACHINE, FAX, EPABX & OTHER PRECIOUS MACHINES, WHICH ONE REQUIRES HIGHLY STABILIZED POWER SUPPLY.
* PRINCIPLE : IT CONSISTS VARIABLE AUTO TRANSFORMER & SERVO MOTOR WITH ELECTRONIC CIRCUIT. A DIFFERENCE OF SET VOLTAGE AND INPUT VOLTAGE IS SENSED BY ELECTRONIC CIRCUIT, DEPENDING ON POLARITY OF DIFFERENCE IT OPERATES A SERVO MOTOR EITHER IN FORWARD OR REVERSE DIRECTION. SERVO MOTOR MOVES WIPER OF AUTOTRANSFORMER & AUTOMATICALLY CONTROL THE OUTPUT VOLTAGE THROUGH ELECTRONIC CIRCUIT.
STANDARD FEATURES :
* INPUT VOLTAGE RANGE :
1. SINGLE PHASE 170 TO 270 V.
2. THREE PHASE 360 TO 460 V.
3. OTHER RANGE ARE ON REQUEST.
* OUTPUT VOLTAGE RANGE :
1. 220 OR 230 V +- 1% & 2%.
2. 400 OR 415 V +-1% & 2%.
3. OTHER RANGE ON REQUEST.
* 0-300 V VOLT METER WITH SELECTOR SWITCH TO INDICATE INPUT AND OUTPUT VOLTAGE.
* AUTO/MANUAL SWITCH TO OPERATE UNIT EITHER AUTO OR MANUAL MODE. A INCREASE/ DECREASE TOGGLE SWITCH IS PROVIDED TO INCREASE/ DECREASE VOLTAGE IN MANUAL MODE. CORRECTION RATE OF 35V/ SEC.
* EFFICIENCY - 95% TO 98% AT FULL LOAD.
* INDICATION : MAINS ON INDICATION & HIGH/ LOW VOLTAGE INDICATION WILL BE PROVIDED ON THE PANEL.
