Automatic High Power Voltage Stabilizer 300KVA AVR 380V 400V with LCD Display
1. Product Introduction
This product is a three phase 300KVA AVR. The rated capacity is
300KVA, with rated input voltage range 304VAC to 456VAC
(380VAC±20%) and output voltage 380VAC. The output precision
of this 300KVA high power voltage regulator is ±2% while the
response time is less than one second when the input voltage
fluctuates less than 15 volts.
As for its applications, the voltage regulator could be used for
large factories, hospitals, schools, and malls etc. It also could
be used with large capacity electrical equipment, like generator,
printer, laser-cutting machine, air compressor, and any appliance
needing stable voltage.
