DPD300-4-12 Power Distribution Box, Dual-Two Inputs

DPD300-4-12 Power Distribution Box, Dual-Two Inputs

This chapter introduces the hardware architecture and features of the DPD300-4-12 power distribution box, and describes how to install and maintain the hardware on the device.

DPD300-4-12 Product Description

This section describes the positioning, benefits, usage scenario, main components, physical parameters, and circuit principle of the product.

Positioning

This product is designed to power devices that need a large number of power lines. It can convert input lines into more output lines so that a few input lines in the equipment room can meet power requirement. Therefore, this product increases power distribution flexibility.

Benefits

  • This product is a 6 U (263.9 mm) power distribution box that complies with the IEC297 standard.
  • It can convert 4 DC input lines into 12 DC output lines.
  • It includes A and B power distribution areas. Each area has 2 DC input lines and each DC input line is converted into 3 output lines.
  • It can be equipped with air breakers whose output current ranges from 20 A to 100 A. Air breaker ports are pluggable bolts and easy to replace.
  • The grounding copper bar in the power distribution box can provide 2 input lines and 12 output lines.
Figure 12-1 DPD300-4-12 appearance

Usage Scenario

The power distribution box can convert 2 or 4 DC input lines into 12 output lines. It can be used in an equipment room that cannot provide enough power lines.

For example, the power distribution box is used to convert 4 input lines into 8 output lines to power the Huawei ME60-X16 that is equipped with 8 PEM modules.

0% RH to 95% RH, no condensing

NOTE:
  • Temperature and humidity are measured at 1.5 m (4.92 ft.) above the floor and 0.4 m (1.31 ft.) in front of the cabinet. There should be no protection board on the front or back of the cabinet.
  • "Short-term" refers to continuous working time that does not exceed 96 hours and accumulated working time per year that does not exceed 15 days. If the working time exceeds either of these values, it is considered "long-term".

Circuit Principle

NOTE:
  • When NEG A1(-) is shorted-circuited to NEG A2(-) and NEG B1(-) is shorted-circuited to NEG B2(-), the power distribution box will provide two input lines and 12 output lines.
  • The changed output power must be larger than or equal to the rated power of the device that is powered by the power distribution box.

X3 Power Distribution Instance

This section describes some power distribution instances.

NOTE:
  • This document describes the examples for installing ME60-X series products.
  • The number of each PEM module can be determined based on a product silkscreen and the primary and secondary power supply diagram.

To ensure power supply backup, connect PEM-As to the OUTPUT A area in the power distribution box, and connect PEM-Bs to the OUTPUT B area in the power distribution box.

Scenario Where a Huawei ME60-X3 Is Equipped with 2 PWR Modules

PWR 1 is connected to any power output in OUTPUT A area of the power distribution box.

PWR 2 is connected to any power output in OUTPUT B area of the power distribution box.

This section describes some power distribution instances.

NOTE:
  • This document describes the examples for installing ME60-X series products.
  • The number of each PEM module can be determined based on a product silkscreen and the primary and secondary power supply diagram.

To ensure power supply backup, connect PEM-As to the OUTPUT A area in the power distribution box, and connect PEM-Bs to the OUTPUT B area in the power distribution box.

Scenario Where a Huawei ME60-X8 Is Equipped with 4 PEM Modules

PEM-A1 and PEM-A2 are connected to A1-1 and A1-2 in the power distribution box.

PEM-B1 and PEM-B2 are connected to B1-1 and B1-2 in the power distribution box.

NOTE:

When the power distribution box powers two ME60-X8s at the same time, the A2-1, A2-2, B2-1, and B2-2 are connected to the PEM modules on the second ME60-X8.
