Variac Type Servo Voltage Stabilizer

The Variac Type Servo Voltage Stabilizer is a new Indian-built unit for industrial and commercial use. It stands on the floor plus has wheels - one person can roll it to the spot and bolt it down. A servo motor turns the variac and keeps the output voltage within ±1 % of the target. It accepts any input from 340 V to 480 V but also delivers an even 400-415 V. The unit works at line frequencies between 45 Hz and 55 Hz and reaches 99 % efficiency at full load. Built-in relays trip on overload, short circuit or loss of a phase - the control board resets itself when the fault clears. The stabilizer protects delicate machines as well as keeps the mains supply within tolerance on the factory floor.
