7. Insulation resistance between the outer casing and the main circuit: not less than 1.5MΩ;

8. The altitude is less than 3000m;

9. Operating environment temperature -20 ° C -50 ° C, ambient humidity is less than 80%.

Working principle   

1.Analyze the attribute characteristics of the leakage and store it in the chip;

2.Once the corresponding feature appears in the power line, the filter coil is started synchronously;

3. At the same time, the identification and alarm system is activated, and the chip processing system allows the inner closed loop (normal power line) to continue to supply power, and the outer closed loop (leakage line) to block;

4. The leakage current at the plugging point is lower than 30mA, and the voltage is lower than 36V, so the electric shock does not hurt people, and the electric shock does not ignite
     Core functions    

Electric shock protection: When the human body touches the 380/220V power supply network in a single phase, the current through the human body is lower than the specified safe current 10mA, and people can get rid of the power supply without causing casualties.

Short-circuit protection: When the single-phase line is short-circuited in the power grid, it will not cause power failure of the power grid, ensuring continuous, safe and reliable power supply.

Leakage protection: When the power supply network is single-phase metallic ground short-circuit, the grounding short-circuit current is less than 30mA, and the energy-saving effect is 99%.

Overload protection: When the current is overloaded due to short circuit or other reasons in the power grid, the current distributed to each electrical circuit is automatically controlled to protect the equipment from damage.

Over-voltage protection: Through the intelligent power control technology, the power grid is stabilized, and the voltage is too high/low, and the power is cut off intelligently.

Aging line protection: 380/220V power supply network will not cause arc spark when single-phase metallic grounding is short-circuited, effectively avoiding electrical fire accidents.

Waterproof protection: When the power grid seeps water and causes a short circuit, the system intelligently controls, continuously, no electricity, no leakage.

Fault alarm: When the grid is faulty, it can intelligently detect the fault type, fault location, automatic alarm, and remote control, and turn off the power.

 Compared with traditional methods    

Traditional safe electricity protection methods: need response time (first hurt and then respond), need to power off (affecting production and life);

Sanleng electricity safety intelligent control system protection: no need of response time (no damage at the beginning), no need to power off (does not affect production and life).

Application Scenario       
       Laboratories, hotels, office buildings, airports, nursing homes, communities, gas stations, banks, etc.
