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.

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.
