2. Description


This product is a three phase industrial voltage stabilizer with 500KVA's capacity. The input voltage is 380V±20% while the output voltage is 380V. The voltage stabilizer features in high voltage stabilization precision, fast response speed, strong load-bearing capability, strong instaneous over-load-bearing capability, full protection functions etc.


The voltage stabilizer is mainly used in industrial areas. It could be used with various electrical equipment, like generator, pumps, machine tools, laser-cutting machine, medical device etc.

3. Protections


① Over-voltage protection: when the output voltage is over 400V, the over-voltage protection will work and the stabilizer would stop working immediately to protect the stabilizer and the load equipment.

② Under-voltage protection: if the output voltage is under 360V, the under-voltage protection will function and the stabilizer would power off so as to protect the equipment.

③ Over-load protection: if the stabilizer is over-loaded, the power would be cut off automatically.

④ Over-current protection: if the load current is over than the rated current, the over-current protection function would be work.

⑤ Time delay protection: there is a five-second time delay before the voltage is output to the load equipment in order to ensure its normal work.
