The Servolink 4 kVA AC Stabilizer is our most popular model, made for 1.5 ton split and window air conditioners, the most common AC size in Indian homes and offices. This relay type (step tapping) automatic stabilizer keeps the voltage reaching your AC within a safe band even when the mains supply rises or drops.

Time delay protection prevents the compressor from restarting too quickly after a power cut, and high/low voltage cut-off disconnects the AC when the supply goes beyond safe limits. A digital display shows the voltage, and the unit mounts neatly on the wall next to the AC.
