2. Protection functions
There are various protection functions provided with the voltage stabilizer. Details are shown through the chart below:
| Protections | How does it function? |
| Over-voltage | If the output voltage is 30V higher than the rated output voltage, the voltage stabilizer would power off the ensure the intacity of the load equipment. |
| Over-load | When the stabilizer is over-loaded, it would cut off the power automatically. |
| Under-voltage |
If the output voltage is much lower than the rated one, the stabilizer or regulator would stop working. |
| Over-current | When the working current is higher than rated current, the product would cut off the power supply automatically |
| Phase failure |
This protection function could be designed if necessary |
| Lack phase |
This protection fucntion could be designed if it's needed |
| Time delay | 5 seconds' time delay is designed with the product to ensure the precise output voltage the load equipment needs |
3. Product Features
