3. Protection Functions

 

① Over-load protection: when the actual load is higher than the rated capacity, stabilizer would power off automatically.

② Over-voltage protection: if the output voltage is 10% higher than the rated output voltage, the stabilizer stops working automatically.

③ Over-current protection: this protection function is the same as the first one, over-load protection. If the load is over rated one, the current would be higher than the rated one too.

④ Short-circuit protection: if there is a short circuit, the stabilizer would also cut off the power automatically to protect the electrical machine.

⑤ Time delay protection: there is a five-second time delay when the stabilizer powers on in order to protect the stabilizer itself.
