MuscleGrid 3 kVA Single Phase Servo Voltage Stabilizer | 100% Copper Wound | 140V-270V Input | Air Cooled | 230V ±1% Output

About 2,400 W, using the standard convention of kVA × 800. In practice that covers about one 1.5-ton air conditioner.

It corrects from 140V to 270V and holds a usable output across that window. Below 140V 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 140V 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.

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.
