DC Power Distribution Unit Rack-mount Terminal Box

DCPD-8

Description:

- DC Power Distribution Unit DCDP-8 is a device used to control and distribute electric power for indoor low voltage DC power contribution system. Mounted in a rack cabinet and connected between the -48V DC power supply and the protected equipment, it can protect the equipment from surge and instantaneous over voltage caused by the outside environment (lightning, electromagnetic radiation interference, etc.) or by the internal subsystems (switching effect, start and stop operation of inductive and capacitive loads)

- Power Distribution Unit (PDU) Rack-mount Terminal Box is used for low-voltage DC power distribution.

- The DCPD-8 PDU Rack-mount Terminal Box is standard 19'' rack mount box, it can install in a standard 19'' cabinet.

- The DCPD-8 PDU Rack-mount Terminal Box is installed between a power supply source and system equipment. It protects the system from electrical pulse and instant over-voltage caused by lightning strike, electromagnetic radiation interference, system switch on/off, or inductive / capacitive load on / off.

- The DCDP-8 PDU Rack-mount Terminal Box is used for distributed base stations, providing power to BBUs and RRUs.

- The DCDP-8 PDU Rack-mount Terminal Box structure port:

* 2 channels DC power inputs are of the rated current value of 160 A.

* 10 channels DC power outputs configure 25 A power breakers.

* 10 channels DC power outputs possess the capability of lightning protection.

Feature:

- Two path of power input, and ten paths of power output for distribution with lightning protection.

- Large current-through capacity and low residual voltage.

- Built-in lightning protection board performs lightning and surge protection on the first power-down LLVD1 output.

- Maximum power input current of 50A, 100A, 160A, and maximum rated current of 10A or 25A for power output.

- Remote signalling alarm interface (dry contact signal).

- IP20 protection degree provided by metal enclosure.

- Indoor Installation with good fire resistance.

- Front leading-out cabling with little space occupation.

- 19 inch 1U rack installation.

- 1 input and 8 outputs.

- Circuit breaker for 8 outputs, can disconnect the circuit when fault or overload happens.

- Easy connection for inputs and outputs wiring.

- Insulation of output connectors.

- Large current discharge capability and low residual voltage.

Specification:

- PWR1 & PWR2: Receives external DC power input (Inside dual DC-input ends are connected together in parallel with the rated current of 160 A).

- Switch (breaker 10*25 A): Controls DC power output.

- DC output (BBU/RRU): Provides power supply for the power distribution module of an indoor Base Band Unit (BBU) or an outdoor Remote Radio Unit (RRU).

- LP_ALM: Provides lightning protection alarm (dry contact output).
