× Non standard models are made to customer's specific requirements to caster any other input voltage range / output 
        voltage / frequency / capacity etc.
     × 3 Phase models with single voltage sensing relay and single drive motor are suitable for fairly balanced supply 
        voltage and load.
     × To over come unbalanced voltage and load conditions, 3 Nos 1 phase units mounted in a single cabinet and 
        connected in star, are recommended.

Built in Features :
     × A Voltmeter with switch to indicate input / output voltages.
     × Long term stability of ± 1%.
     × Output setting - ± 5 Volts by a lockable potentiometer.
     × High efficiency above 95%.
     × Indications for "Power ON", "Input too low" & " Input too high".
     × A drive motor of special construction having high torque, low speed output with instant start / stop / 
        reverse characteristics.

Construction : 
Lower capacity units, up to 50KVA are in air cooled single unit construction. Higher capacity units will be in two piece construction for the convenience of transportation & installation. Inter connecting cables / bus bars will be provided with the equipment. Both sections will be floor mounting type, and either one or both may be oil cooled depending on requirement.

Operation : 
The voltage stabilizer works on a simple principal of adding or a subtracting a voltage to the supply voltage in appropriate quantity to correct it to the required level. This voltage to be added or subtracted is obtained from the mains itself, using a continuously variable voltage auto transformer, driven by a servo motor under the control of voltage sensing relay. This relay sense the output voltage continuously, compares with a highly stable reference and directs the drive motor to correct the output voltage to the set level.

Salient Features : 
     × Fully solid state voltage sensing relay using professional grade components.
     × No relay - No chattering - No RF interference.
     × Fast acting.
     × Fully tropicallised, most suitable for weather conditions prevailing in Indian sub-continent.
     × Variable transformer and voltage sensing relay-most important components are made in house under strict quality       
         control.
     × Variation in the supply, frequency and load p. f. has no effect on the output voltage setting.
     × No harmonic distortion is introduced by the stabilizer.

Optional Features :
     × Over voltage / under voltage protection relays.
     × Over load protection relay.
     × Remote sensing facility.
