From the supplier
- Product Introduction
DK-DC20 modular DC power supply series surge protective device (SPD) is designed and manufactured according to IEC61643 standard. It is accordance with the criterion of surge protective devices connected to low-voltage power systems–requirements and test methods. It is designed as module and 35mm din rail mounting. With working indication window, temperature control circuit breaker and built-in over current protective circuit, it can automatically release to avoid fire danger when it breaks down. It consists of remote alarm connector for remote monitoring. It is suitable for communications, TV broadcasting, computer room, automatic control, mechanical and electric control, mechanical and electrical equipment, and related DC power equipment.
