JINLI Surge protective device adopts the excellent nonlinear component with over-voltage protection. The SPD has a high impedance and low leakage current when no surge is present, can have a sudden change within nanosecond time in impedance to a low value in response to a voltage surge, limiting the surge amplitude to the safe working range of the equipment, and releasing the surge energy into the ground. Thus, the Surge protective device quickly becomes high impedance, and does not affect the working of the power system.

AC type Surge protective device is used in AC power supply system (50/60HZ) and low-voltage control system to protect from lightning strike and transient over-voltage. The maximum continuous operating voltage (Uc): 175V, 275V, 350V, 385V, 440V, 485V, 750V.

DC type Surge protective device is used in all kinds of DC power system, such as industrial control system, communication system and fire control system with DC voltage of 24V, 48V, 110V, 220V etc. And also available for 1000V and 1500V DC power system of photovoltaic power generation equipment in DC side, DC combiner box, inverter in DC side, etc.
