FAQ
Do voltage stabilizers require much maintenance?
Equipped with roller carbon brushes, our voltage stabilizers are maintenance free. But yearly ocular (visual) inspections are strongly encouraged. Any electrically trained technician is more than capable of carrying out these simple maintenance tasks – with ease.
Do voltage stabilizers save money?
Voltage stabilizer with voltage optimisation technology could yield average energy savings of up to 25%.

What is the difference between voltage regulator and stabilizer?
Voltage Stabilizer: It is a device or circuit which is designed to deliver constant voltage to the output without in changes in incoming voltage. Voltage Regulator: It is a device or circuit which is designed to deliver constant voltage to the output without in changes in load current.
What does a voltage stabilizer do?
A voltage stabilizer acts as a protective shield and reduces chances of malfunction. It also helps increase the life of various appliances. Installing a voltage stabilizer is essential to protect expensive electrical appliances such as Air Conditioners, television, refrigerator and computers.
