DPD125-12-24 DC Power Distribution Box

DPD125-12-24 DC Power Distribution Box

This section describes the hardware features and installation and maintenance of the DPD125-12-24 DC power distribution box.

DPD125-12-24 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 4 U (177.8 mm) power distribution box that complies with the IEC297 standard.
  • It can convert 12 DC input lines into 24 DC output lines.
  • It includes A and B power distribution areas. Each area has 6 DC input lines and each DC input line is converted into 2 output lines.
  • It can be equipped with air breakers whose output current ranges from 60 A. Air breaker ports are pluggable bolts and easy to replace.
  • The grounding copper bar in the power distribution box can provide 6 input lines and 24 output lines.
Figure 13-1 DPD125-12-24 appearance

Usage Scenario

The power distribution box can convert 6 or 12 DC input lines into 24 output lines. It can be used in an equipment room that cannot provide enough power lines.

Ambient humidity

Long term

5% RH to 85% RH, no condensing

Short term

5% RH to 95% RH, no condensing

Relative storage humidity

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:
  • You can change the power system of the product to 6-channel input and 24-channel output by copper fitting NEG A1(-) and NEG A2(-), NEG A3(-) and NEG A4(-), NEG A5(-) and NEG A6(-), RTN A1(+) and RTN A2(+), RTN A3(+) and RTN A4(+), RTN A5(+) and RTN A6(+), NEG B1(-) and NEG B2(-), NEG B3(-) and NEG B4(-), NEG B5(-) and NEG B6(-), RTN A1(-) and RTN B1(+) and RTN B2(+), RTN B3(+) and RTN B4(+), and RTN B5(+) and RTN B6(+).
  • 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.

X8A Power Distribution Instance

This section describes some power distribution instances.

NOTE:
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.
