Other details of Variac Type Servo Voltage Stabilizer :-

Our firm is occupied in producing a extensive range of Variac Type Digital Servo Stabilizer. Our digital stabilizers are ideal for all kinds of electrical and electronic devices. Most recent technology is absorbed by us to fabricate these digital stabilizers in a variety of configurations. Our Variac Type Digital Servo Stabilizers are furnished with most recent Digital Micro Processors Controllers and have been intended to give a steady yield voltage with constancy of +/-1%.

Voltage oscillations can decrease the competence of all kinds of electrical and electronic device and harm them. Our Variac Digital Voltage Stabilizers defend your appliances from voltage surges and offer a neat, synchronized AC power supply in atmospheres with undependable, fluctuating mains contribution. In the occasion of a surge in the electrical energy, the stabilizer will even out the yield to make sure that the voltage attaining your device stays constant at 220V (+ 6%) and 220V (+ 9% in ER Models) within the operating array of the unit.
