Static Voltage Stabilizer or Static voltage regulator or IGBT Voltage Stabilizer is same as servo voltage stabilizer but without any moving part Like Servo Motor / Variac with correction voltage 4000V to 8000V Within the duration of one waveform i.e. 20ms The chopping frequency ranges around 20 kHz that ensures absolute silent operation of the SVS and a pure sine wave output. The voltage correction speed of static voltage regulators can be up to 500 times faster than a servo stabilizer. But in Servo Stabilizer correction in output voltage achieve with help of moving Brush Through servo motor hence correction speed 100V/S Maximum (Depending on Variac Gear and Motor Gear). available for indoor type as well as an outdoor type.
