Profile: Nantech Power Systems is engaged in manufacturing of online UPS, line interactive UPS, inverters and servo stabilizers. We are an ISO 9001:2008 certified company. We also offer power factor controllers and constant voltage transformers. Servo voltage stabilizer provides constant output voltage to load. The main purpose of voltage stabilizer is to receive and convert a fluctuating AC voltage of low or high amplitude to an almost constant voltage at the output. Voltage variations which have become a common phenomenon in power supply systems cause havoc in advanced electronic equipments.
