Product Description

70KVA High Power Automatic Voltage Regulator IP20 Industrial Class,380V 50Hz High Efficiency and Energy Saving​




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.





Widely used in posts and telecommunications, market, elevator, hospital, school, printing,negotiable securities and so on where all need normal voltage situation. And  SBW, DBW Europe Technology High Precision Electronic voltage Stabilizer also can be matched with big and medium industry and mining enterprise workshops, some power supplies and the key equipment and the single.
