1200 W DC Power Module (PDC-1K2WA)
Version Mapping
1200 W DC power modules include PDC-1K2WA-B (B: back-to-front airflow, air exhaust on power module panel) and PDC-1K2WA-F (F: front-to-back airflow, air intake on power module panel).
Table 3-61 describes the mapping between switch models and 1200 W DC power modules.

Appearance
Figure 3-55 shows the appearance of a PDC-1K2WA-B power module, and Figure 3-56 shows the appearance of a PDC-1K2WA-F power module.
Function
PDC-1K2WA-B and PDC-1K2WA-F power modules use different airflow designs but have the same functions. Table 3-62 describes the functions of a 1200 W DC power module.
Function |
Description |
|
|---|---|---|
Input protection |
Input undervoltage protection |
In this protection state, the power module stops supplying power. When the input voltage restores to the normal range, the power module automatically resumes power supply. |
Input overcurrent protection |
In this protection state, the power module stops supplying power and cannot automatically resume power supply when the input current restores to the normal range. |
|
Output protection |
Output overvoltage protection |
In this protection state, the power module supplies power intermittently. When the output voltage restores to the normal range, the power module automatically resumes power supply. |
Output overcurrent protection |
In this protection state, the power module supplies power intermittently. When the output current is limited within a range, the power module automatically resumes power supply. |
|
Output short-circuit protection |
In this protection state, the power module supplies power intermittently. When the short circuit is removed, the power module automatically resumes power supply. |
|
Overtemperature protection |
When the temperature of the power module exceeds a specified threshold, the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply. |
|
Heat dissipation |
|
|
Hot swap |
Supported |
|
When a power module enters overtemperature protection state, take measures to lower its temperature. The power module can automatically resume power supply when the temperature falls within the normal range.

Status |
Description |
|---|---|---|---|
STATUS: power indicator |
Green |
Off |
The power input is abnormal (for example, no input, overvoltage, or undervoltage) or the power output is abnormal (for example, overvoltage, overcurrent, short-circuit, or overtemperature). |
Steady on |
The power module is working normally. |
