380V 400KVA Three Phase Automatic Voltage Regulator For Industrial
Appliance
1. Product Profile
The whole name of this product is three phase high power
compensation voltage stabilizer or regulator. The rated capacity of
this product is 400KVA. The model of it is SBW-400KVA. Normally,
the power capacity of this kind of product could be 50KVA to
2000KVA. As for the voltage, the input voltage of it ranges from
304V to 456V. The output voltage is 380V. However, the input and
output voltage can be customized according to your needs.
The applicable circumstances of this product are numerous. For
instance, it can be applied in industrial factories like steel
plant, mining plant, and other relevant places. Then it could be
used to stabilize the voltage of school, hospital, or other places
with fluctuating voltages. Also, it could work with many kinds of
electrical equipment to stabilize the voltage when the appliance is
working.

4. Product Features
① Higher load-bearing capability: this series of product has a
better load-bearing capability than normal three phase voltage
stabilizers.
② Lower risk of machine malfunction: this kind of stabilizer is
more stable than normal one.
③ Longer lifetime: It could work for nearly ten years or even more
if you use and maintain it in a correct way.
④ Two working models: you can change the working models of the
voltage stabilizer between power supply and stabilizing the voltage
manually.
