Product Description

380V Three Phase Voltage Stabilizer Electrical SBW Series 500KVA​



Principle & Characteristics

This product is designed and developed with the international advanced compensation technology.

It can keep the output voltage in steady state automatically when the network voltage fluctuated or

the load current varied, which can ensure the consumer run smoothly. It has the advantage of large

capacity, high efficiency, no waveform distortion, simple operation and maintenance, reliable running,

full- capacity output under tower input voltage if compared with other voltage stabilizer. It is provided

with over-voltage, over-current, phase sequence and so on protection function.


Scope of Application

It is suitable for electric supply in small-sized plant, workshop and department in middle, large-sized mining enterprise, it can be widely used in the precision machine tool, precision instrument, test device, elevator, imported electromechanical device, production flow-line in the mining enterprise, oil field, railway, building site, school, hospital, hotel, scientific research department and so on, it is also suitable for the user in the LV electric network end with low power voltage and big wave range
