DC Power Distribution Unit 19'' Rack-mount Terminal Box DCPD-10 for RRU BBU

DC Power Distribution Unit 19'' Rack-mount Terminal Box DCPD-10 for RRU BBU

Description:

- DC Power Distribution Unit Rack-mount Terminal Box DCPD-10, installed in 19’’cabinet and connected between - 48 VDC power supply and equipment, is a distribution unit and surge protection equipment, providing multipath power output.

- It is suitable to indoor low-voltage DC power distribution system for protection of equipment from surge and transient over-voltage caused by outside environment (such as lightning, EMI, switching effects of the system) or internal environment (power on and off, startup or shut off of inductance and capacitance loads, etc.)

Feature:

- 19 inches, 1U standard rack installation;

- 1 input with two parallel ports and 10 outputs;

- With fuse tube, can disconnect the circuit when fault or overload happens

- Good insulation for output terminals

- Large discharge current and low residual voltage

- With Indicator light for each fuse tube and surge protection

- DC Power Distribution Unit Rack-mount Terminal Box DCPD-10 provides two channels of -48V DC power input with a total current of no more than 200A;

- It provides 6 channels of DC power output, each of which is controlled by an independent fuse to support a rated current of 25A;

- It also provides 4 channels of DC power output, each of which is controlled by an independent fuse to support a rated current of 42A;

- It provides lightning protection and surge protection for the power output through a built-in lightning protection board.

Application:

- The DC Power Distribution Unit Rack-mount Terminal Box DCPD-10 is usually applied to distributed base station systems, in which it powers the BBU and RRU/AAU. The power cable of RRU should be shielded and the shielded layer must be connected to the outdoor grounding bar before being connected into the cabinet or equipment room.
