Product Description

Contactless Voltage Stabilizer 3 Phase 50 Kva Avr Auto Voltage Regulator


1. Product Profile


This kind of product is called contactless stabilizer, or non-contact stabilizer. It could be three phase or single phase. This product here is three phase one, of which the input voltage is 304V to 456V while the output voltage is 380V. Both the input voltage and output voltage can be tailored based on your needs. The product respond very quickly to stabilize the voltage, which only needs less than 30ms to help voltage stabilization. Its main parts include isolation transformers, circuit boards, silicon-controlled modules, LCD display and other essential parts. Its output accuracy can be customized from 1% to 3%.

About Protection Functions
Over-voltage When output voltage is 10% more than rated one, stabilizer powers off automatically
Under-voltage When output voltage is 15% less than rated one, stabilizer powers off automatically
Over Load When output current is over the rated current, stabilizer powers off automatically
Phase Dislocation When three phase dislocates, stabilizer gives an alarm and powers off subsequently
Phase Lack When three phase voltage lacks one pahse, stabilizer gives an alarm and powers off subsequently
Short Circuit When the loading equipment is in a short circuit, stabilizer powers off automatically

3. Main Components and the Functions


First, isolation transformers: a three phase contactlesss stabilizer has at least nine isolation transformers, which play an important role in compensating the voltage for the whole circuits. 


Second, circuit borads: they are advanced integrated circuits, which features in fast speed of transmission and sound performance. 


Third, Silicon-controlled modules: it helps to regulate the voltage with no noise.


Fourth, AC Contactor: it respond quickly if it's over-voltage or over load.


Fifth, Iron enclosure: it protects the whole parts of stabilizer, which facilitates a longer life of stabilizer.


Lastly, there are also many small parts, which plays an significant role in helping the stabilizer to work normally for a long time.


4. Applications


① CNC equipment     


② Laser-cutting appliance      


③ SMT equipment       


④ Medical device   


⑤ Railway stations      


⑥ Subway Stations     


⑦ and other places needing no-noise stabilizer.


5. Correct Operation


① Power off the stabilizer and the electrical equipment firstly. 


② Connect wires according to the indications on the wiring board. 


③ Turn on the power of stabilizer and the stabilizer enters into a condition of self-checking.


④ Turn on your equipment after the input voltage is in the range of rated input voltage.


⑤ Turn on your houshold appliance or industrial equipment in succession.


⑥ Turn off the power if you do not use the stabilizer.
