Product Introduction
DK-20 Modular Power Supply Series SPD is designed according to IEC standards. It is designed as module, with features of good seal ability and 35mm din rail mounted. With working indication window, temperature control circuit breaker and built-in over current protective circuit, the modular SPD canl automatically release to avoid fire danger when it breaks dowm. It consists of remote alarm connector for remote monitoring. The main module and the base are replaceable. It can be used for lightning protection of L-PE, N-PE(4P) or L-N-PE(3+1).
