Well, Excell Voltage Stabilizer is an electrical appliance that functions on AC power supply to provide constant output voltage.
There are many types of voltage stabilizers. However, only two types are widely used across the world. The simplest one is “Relay” based. It is basically a transformer, wherein the input supply is given to primary windings and output is received from secondary windings. It adjusts output voltage by adding or subtracting windings of the transformer coil, by activating electromagnetic switches (also known as relays). In this type, output is not accurate.
The second type, Excell Voltage Stabilizer is much more precise. It works on the same technology i.e. principle of transformer. But here the number of windings are added or subtracted by precisely adjusting the position of contact on the coil through stepper motor.
By changing the position of contacts, it (a) boosts the voltage and provides proper output when input supply is low, (b) reduces the gives correct output that it is designed for, and (c) maintains constant output voltage even when the input AC voltage is fluctuating.
In simple terms, to protect and prevent failure of air-conditioners, computers, and such electrical gadgets, you must connect them through Excell Voltage Stabilizer.
