Voltage stabilizer is an electrical device which is used to constantly feed voltage to the electrical appliances such as AC, computers, refrigerators, etc. The fluctuation of voltage is continuously monitored by VVS. Our stabilizers keep the current fluctuation from rising and lowing down when it reaches to the electrical equipments. As soon as the input voltage rises or falls down the range of input voltage, VVS disconnects the output to protect the equipments from the load. Once the main voltage gets back in the acceptable voltage range, VVS reconnects the output for further current passing. Thereby, microprocessor controlled circuit unit, with its powerful features is named as VVS.
