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.

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


① Fast response speed: one second response time when input voltage 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.
