MuscleGrid 15 kVA Three Phase Servo Voltage Stabilizer | Oil Cooled | 240V-470V Input | 400V ±1% Output

About 12,000 W, using the standard convention of kVA × 800. In practice that covers a large home, shop or clinic.

It corrects from 240V to 470V and holds a usable output across that window. Below 240V it cuts out to protect the load rather than pass an unsafe voltage through. Buy for the worst voltage your area actually sees, not the average — if your supply falls below 240V in summer, ask us for a wider-range model.

This is a servo stabilizer. It drives a motorised variac that continuously hunts for 230V, holding output to roughly ±1%. Correction is smooth rather than stepped, which is what industrial, medical and precision equipment needs.

The transformer is immersed in oil, so it runs far cooler under sustained full load and lasts longer where the stabilizer works hard all day. Air-cooled units are lighter and cheaper, and are the right choice for domestic and light commercial duty.

Yes. The output is held off for a few minutes after supply returns, so the compressor never restarts before refrigerant pressure has equalised — restarting into unequalised pressure is what kills compressors.

Three years, covering manufacturing defects and internal component failure, with service from our own centres in Delhi and Meerut.

Yes, a GST invoice is issued on every order and the price shown already includes GST.
