Model Number:
TB(SG)-50KVA
50KVA Automatic Voltage Regulator 3 Phase 60Hz 50Hz Adjustable Output Voltage
1. Product Overview
This product is an automatic voltage regulator with 30KVA rated capacity. It is an integrated electrical equipment composed of two major parts: transformer and regulator. The input voltage is 380V 3P while the output is 0-1200V adjustable. Of course, the input voltage and the output voltage could be customized according to your request.
The normal three phase voltage regulator adjusts voltage from 0V to 430V. So if you want a product with 0-1200V or wider range adjustable, there should be a transformer working with the regulator together. The transformer could be customized with primary voltage 380V, output voltage 1200V. When the transformer co-works with the regulator, the output range could be 0-1200V.
There are two buttons controlling the output voltage: stepping up and stepping down buttons.

3. Product Features Elaboration
① Integrated function of voltage transformation and voltage regulation.
② High precision: you could adjust the voltage very precisely.
③ LCD display of input and output voltage: two LCD displaying meters are designed with the product to show input and output voltage respectively. It's very convenient for you to get input and output voltage data from the meters.
④ Imported silicon steel sheet: as an important part of the transformer, imported high quality silicon steel sheet strengthens electricity conductivity.
⑤ Painted iron enclosure: it effectively protects the transformer and the voltage regulator.
⑥ Stepping up and stepping down button: it's half auto design. You don't have to turn around the rotary switch to adjust the voltage. Instead, pressing the buttons could realize voltage adjustment.
4. Product Display
This picture shows the exterior design of the product. There are two displaying meters showing input and output voltage. Two buttons (stepping up and stepping down) to control the output voltage. The omni-directional wheels make it easier to move the product.
This pictures perfectly shows the inner structure of this regulated power supply. It is composed of two major parts: transformer and regulator.
