Product Description

1.The distribution method adopts secondary distribution principle, input uses total fuse,

 and output adopts branch fuse or combination of fuse and DC air switch. 

2. All key components use products passing CCC, with safe and reliable use. 

3.The output loop number is determined by customer demands. 

4.It can match voltage and current display and power supply working indication function. 

5.C and D grade power source surge protectors with different specifications and 

protection modes can be allocated according to customer demands, and power source 

surge protector integration is installed nearby the box, and has short line distance

 and good protection effect. 

6.The surge protector has large flow path, low residual voltage and rapid response time. 

7.It can match lighting stroke count, DC power failure alarm and other auxiliary 

functions. 

8. The box made of excellent cold-roll steel sheets has compact structure and 

attractive appearance. 

9.It has good electrical insulation function and protection earthing system. 

10. It has convenient use and maintenance, and wire inlet and outlet on the top 

and bottom, and can select according to requirements of users' inlet wire method.

It is used for distribution and management of indoor direct-current power supply

 in communication machine room, and providing direct-current power supply to 

communication equipment in machine rooms. Its interior uses famous brand circuit 

breakers (Siemens, ABB, Chint), made for communication base stations and machine rooms.
