● The rapid heat conduction of the low temperature solder joints makes the tripping more timely and accurate;

    ● Mechanical arc shielding to make arc extinguishing more effective (the creepage distance is as high as 12mm after disconnection);

  ● The tripping device does not occupy additional space, so that it does not affect the discharge capacity of the SPD;

       ● Ensure that the trip device operates before the MOV is damaged, so as to avoid fires caused by a short MOV.



 Zhongpeng Surge Protection Device (SPD)—Process Advantage



EYZAO SPD is 100% potted encapsulation


1. Better tightness;

2. The production process is complex and the cost is high;

3. Better stability, to ensure that the solder joints are free from external forces;

4. Effectively prevent the deformation of the MOV and the plastic shell to ensure its sealing and insulation performance, especially

It is used in a high temperature environment .





Under the conditions of high temperature and humidity, the encapsulated MOV is more likely to degrade, and when a surge comes, the SPD is more likely to burst.

Super high overvoltage tolerance


EYZAO SPD has excellent transient overvoltage withstand capability. Under the condition of ultra-high over-voltage, it can trip safely without catching fire, and give correct instructions. It is unique in the industry.

Take the 320V SPD as an example, add (750V) on both sides of the SPD 3 times the normal voltage (230V), 2.3 times the Uc value of the SPD (320V), the state of the SPD is as follows:


Product advantage.png

The requirements of IEC61643-11 for this product are only 337V/5s tolerance and 440V/2h failure mode. EYZAO SPD far exceeds this requirement, which is of great significance in practical applications.
