Driven by AC power, offered Three Phase Voltage Stabilizer is reckoned for around 800 KW to 1600 kw load capacity range. Its output voltage is 3800 V and maximum input voltage is 456 v. This stabilizer adopts LED or LCD based display mechanism. Compensation technology of global standard has been used to design this Three Phase Voltage Stabilizer. This system can maintain stable condition of output voltage automatically during fluctuation in voltage or during variation in load current. It is protected against over current and over voltage.
