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

fluctuates less than 10% of the rated voltage.
② High precision accuracy: the output voltage precision is ±2% to
ensure the normal performance of the load equipment.
③ Full protection functions as mentioned in part two.
④ Suitablity for customization: input and output voltage,
protection functions, enclosure color and other designs are
acceptable.
⑤ Suitability for various loads: its load bearing capability is
very strong.
