Power Supply Series Modular Surge Protective Device
(Class I / Type 1)
1. Product Introduction
DK-50G modular power supply series Surge Protective Device (SPD) is designed according to IEC61643 standard. It conforms with the standard requirement of low-voltage surge protective device--Part 1: product performance requirement and testing method of low-voltage power distribution system. It is designed as module with 35mm DIN-Rail Mounting. It takes the advantage good sealing. Every lightning protection module adopts temperature control technology and built-in over current protective circuit. When the lightning protection module is degradation, it can release automatically, which can avoid fire danger. This lightning protection module has build-in remote alarm connector for remote monitoring. The protection lightning mode is L-PE, N-PE.
