Introduction

DKG-20 is a kind of module DC power surge protection device(short for SPD), which is installed in the front end equipment of photovoltaic DC power distribution system. It can prevent the system and equipment from the permanent damage or  short interruption caused by induced over-voltage, over current, and other induced surge voltage. The product is designed, produced and tested according to GB18802.1 standard, and it is strictly in accordance with ISO9001 quality control system. Adopted high temperature and resistant flame retardant plastic shell, with the features of good sealing, good appearance, easy installation, dust-proof, anti-corrosion and flame retardant, this product can work stably under a harsh environment.

It is designed as module with 35mm din rail mounting. It has working indication window in each line. When working indication window turns red, the SPD breaks down. With temperature control circuit breaker and built-in over current protective circuit, this modular SPD can automatically release to avoid fire danger when it breaks down.The optional remote alarm function is convenient for remote monitoring and automated management. The main module and the base are replaceable. It can be used for lightning protection of +-－-PE.
