SBW 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.
There are heat dissipation fans and heat emission holes for temperature lowering. 
This part shows the wiring panel of the automatic voltage regulator stabilizer. There is main circuit breaker, bypass switch, input wiring terminals and output wiring terminals.
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.
