AC Power SPD

The surge protector is designed to prevent transient surge conditions. Large single surge events, such as lightning, can reach hundreds of thousands of volts and can cause immediate or intermittent equipment failure. However, lightning and power anomalies account for only 20% of instantaneous surges. The remaining 80% of the surge activity is generated internally.

Our AC surge protectors/SPD overvolted protection and support long-term system reliability by absorbing large amounts of transient energy while maintaining low clamp voltages.

It can provide high-quality, safe and reliable surge protection for devices in power supply systems.

It was widely used in petrochemical, gas, environmental protection and new energy industries.

FAQ of AC Surge Protector

How to select SPD for AC power？-

1. Maximum continuous operating voltage Uc

2. Discharging capacity

3. Combination

What is In and limp means?-

Nominal discharge current (In) is the Max. Anti-surge Current Capacity.

Impulse current (Iimp) is the current that defined by the three parameters: Ipak, Q, and W/R, typically with a waveform of 10/350us.
