Product Description

Industrial Device Automatic Voltage Regulator 50 KVA Three Phase 380V 50Hz


1. Product Introduction


The automatic voltage regulator is a three phase industrial voltage stabilizer. The rated capacity is 50KVA, with input 380V±20% and output 380V±2%. The product is full automatic by regulating fluctuating voltage automatically, without manual operation at all.


The major parts of this stabilizer is made of high-quality components, which could lower the risk of machine malfunction brought by problems of small parts. The main components include copper coil, aluminum coil, carbon brush, circuit board, servo motor, enclosure etc.


2. Applications


The 50KVA three phase automatic votlage regulator is mainly used in industrial areas. It could be used for voltage stabilization for electrical equipment.


For example, it could be used to regulate voltage for cutting machines. When the cutting machine starts working, the start impact is very large. At this time, the voltage may fluctuates greatly because the instaneous current is big. With a regulator, the voltage could be stabilized at 380V or any value that you need.


Then, it could be applied with pumps. When several pumps works at the same time, the voltage may be unstable. The voltage regulator could work at this time to stabilize the voltage.


Certainly, here are just two examples showing where the voltage stabilizer could be used. As long as there is unstable voltage, the product could be used as a stable votlage power supply.
