Product Description

SBW/DBW Automatic Industrial Voltage Regulator Three Phase 120KVA,High Quality,High Efficiency and Energy Saving​



Working principle

SBW, DBW Europe Technology High Precision Electronic voltage Stabilizer is designed for stable AC voltage by inducing and absorbing the Western Europe advanced the same time combined our national condition. When the outside power supply network voltage fluctuates or the load changes to make the voltage undulation, it can automatically maintain the output voltage to be stable.


Comparing with other type voltage regulator, this series product has big capacity, high efficiency undistorted waveform, steady regulation voltage and so on the merit,widely suitable load, withstand instantaneous and overload, long-term continuous working, manual/automatic switching, equipped with the over-voltage protection, lacking phase, phase sequence protection and mechanical breakdown automatic protection, as well as small volume, light weight,convenient usage and installment, reliable movement and so on merit, (two kinds of digital display and instrument indication)

We are Manufacturer which specialized in Servo Voltage Stabilizer, Uninterruptible Power Supply (UPS), Active Power Filter, etc for nearly 40 years. And be vendor of Mitsubishi Elevator in East Africa, GE, Emerson.
