Surge protective device soldered directly onto PCB is voltage-limiting type and mainly used to prevent surge overvoltage in AC/DC power supply circuit, which equipped with safety disconnection device and status indicator. Normally, the indicator window is green, and will turn to red under malfunction and generate remote alarm signaling(Normal closed electrical independent contacts).
It is applicable to
220V/380V AC power system or 670V (<670V) DC system. In is10kA and Imax is 20kA. It can increase nominal discharge current by parallel connections. Different protection modes are available according to the requirements of customers. Surge protective device is soldered directly onto PCB of various electrical and electronic equipments, such as AC circuit of charging pile, inverter, communication equipment, household appliances etc. as the second or third stage protection.
