Servo Voltage Stabilizer comes with the facility of Automatic as well as Manual mode. You can change the mode by toggle switch. Mode by default is “Automatic”. If by any chance, mode is shifted to manual side than Voltage regulation shall not be possible through Servo.

Automatic Stabilizer is a relay based conventional type Stabilizer, which corrects the voltage upto lesser accuracy i.e. ±8%, when compared to Servo Voltage Stabilizer which is servo motor based stabilizer whose accuracy is ±1%, or as prescribed by the manufacturer.

The cost is moderately higher but the payback is less than a year.

We need certain inputs from customer end:
a. Load in KW and in kVA
b. Lowest Voltage
c. Highest Voltage
d. Required Voltage
After all these inputs we could suggest you the right Servo Stabilizer for you.

No, you don’t have to purchase an extra Automatic Relay based stabilizer if you already purchase a Servo Stabilizer with sufficient capacity.

Wear and tear of electrical appliances at higher voltage is higher and in turn increases the current drawn thus load on the meter. This can be checked and corrected by applying our Servo Voltage Stabilizer on the main line.

Carbon wiper moves for correction of voltage. And at night as there is complete silence, you could feel the sound of carbon wiper or motor used to correct the voltage; no moving part other than wiper is there inside it.
