SBW-F automatic voltage regulator/stabilizer features in fast response speed, high efficiency, high output accuracy, automatic voltage regulation, no additional waveform distortion, sound voltage regulation performance, and suitability for constant work etc. It is designed with various protection functions, including over-voltage, under-voltage, over-current, phase lack, and phase failure protections etc.


We use LCD multi-functional display screen to indicate the following data: input voltage, output voltage, output current, and working status etc. We could monitor the figures directly, which is very user-fiendly. Besides, the buttons on the screen are for function setting, which makes the AVR more flexible.
These four parts are the major elements for this three phase automatic voltage regulator stabilizer. High quality parts helps to facilitate the stable performance of the AVR.

The inner structure of this SBW-F-1000KVA automatic voltage stabilizer/regulator for your reference.
It mainly contains copper column for voltage regulation, transformer for voltage compensation, servo motor, main switch, bypass switch, display screen, carbon brush, cabinet, heat draugt fan, bus bar, and other necessary parts.
There are various protection functions: over-voltage protection, under-voltage protection, over-current protection, short circuit protection, over-load protection, phase failure protection etc, thus to ensure the safety of the voltage regulator/stabilizer itself and the latter load equipment.


Ewen Electrical has been dedicated to designing customized products for our customers. If you have specific technical requirements, the AVR could be customized according to your needs.
