Product Description
Product Introduction
DK-DC Modular Power Supply Series SPD is designed according to IEC standards. It complys with the requirements of GB18802.1-2011 Low-voltage surge protective devices--Part 1: Surge protective devices connected to low-voltage power distribution systems--Requirements and tests. 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 can automatically release to avoid fire danger when it breaks down. 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 +(1)-PE,-(2)-PE(2P).
