Automatic 3 Phase Ac Voltage Stabilizer 400KVA 380V 50Hz With LCD Display
1. Product Profile
The product is a three phase automatic voltage regulator, with rated capacity of 400KVA. The input voltage range is 380V±20% while the output voltage is 380V±2%. The rated capacity, input voltage, and output voltage could be customized according to real needs.
The working theory of this stabilizer goes like the following description: if the input voltage fluctuates from a certain value to a certain value, it could be stabilized to a certain value through this voltage stabilizer. The input voltage range and the output voltage could be tailored. When the input voltage deviates from the city power, the voltage stabilizer reacts quickly to it. It starts to regulate the voltage mainly through the regulating column and compensating transformer. It could stabilize the voltage within two seconds.
