Stabilizer

Servo Voltage Stabilizer
Servo voltage Stablizer (SVS) is a linear type of voltage regulator that can deliver output voltage of 1% variation and can correct the fluctuating voltage with 20 V/Sec correction speed.

In DIGITECH SVS we can guarantee overall efficiency of more than 98% and is such designed that harmonic distortion of various kinds of load do not effect the operation.

In DIGITECH SVS with AC servo motor operated high voltage corrector are designed for operation on fluctuating incoming mains for single phase/three phase balanced/unbalanced supply and load for providing stable output.

The output voltage is compared with built in stable reference voltage source. The solid state control curcuit operate the motor whenever the output voltage falls or rise beyond a preset voltage. The isolated secondary winding of the buck boost transformer in series with the main supply. While its primary winding is connected to the AC motor controlled auto transformer. Due to change in output voltage, motorised auto transformer delivers controlled voltage to the primary of the back boost transformer and therfore, secondary voltage so that the output voltage returns to set level.

Constant Voltage Transformer
Constant Voltage Transformer (CVT) is very precise type of voltage stabilizer with output regulation as good as 0.05%. It is actually noiseless stabilizer without moving parts inside. Since it is purely electrical equipment without any Active Electronic Components and complex mechanism, no maintenance is required. It can also prevent devices from very harmful unwanted spikes and notches. Besides this, it provides complete isolation from input to output that helps to make the equipment electrically safe for operation. CVT works on ferro-resonance principle. We manufacture CVT range from 250 VA to 5KVA, which could be applied efficiently in hospitals, laboratory, computer, epabx, workshops etc.
