Electronic Voltage Stabilizers

About Voltage Stabilizers

Power supply is erratic at most places in India, with voltage fluctuating in both directions (up and down) at many places frequently. These voltage fluctuations can damage appliances, there by causing them to end much before their normal useful life. When voltage goes down, electric current in the appliance increase, which can result in burning of the appliance. A Voltage Stabilizer is an electriconic appliance used to feed constant voltage current to Electrical & Elecronic gadgets like CTV's, LCD / LED TV's, Refrigerators, AC's and Computers, and protects them from damage due to voltage fluctuations.

It works on the principle of a transformer, where the input current is connected to primary windings and output is received from secondary windings. When there is a drop in incoming voltage, it activates electromagnetic relays which add to more number of turns in the secondary winding, thus giving higher voltage which compensates for loss in output voltage. When there is rise in the incoming voltage, the reverse happens, and, thus, the voltage at the output side remains almost unchanged.
