The Huawei PDC400S12-CB is a 400W 12V industrial-grade high-power, high-density switching power supply module launched by Huawei. Its core advantage is its precise adaptation to high-power scenarios and Huawei's high-end equipment—it delivers 400W output power, a stable 12V output voltage with low ripple, and supports a wide input voltage range of 100-240V with a conversion efficiency of ≥90%. It adopts a high power density design and uses military-grade components, integrating multiple enhanced protections against overvoltage, overcurrent, short circuit, lightning surge, and overtemperature. Its operating temperature range covers -25℃ to 65℃, and it supports 24/7 continuous heavy-load operation with an annual failure rate of <0.02%. It is perfectly compatible with Huawei's S5731S enhanced high-end model, S6730-H series switches, centralized power supply for large data centers, and high-power industrial control equipment.

Input overvoltage protection and 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 overvoltage protection
In this protection state, the power adapter stops supplying power intermittently. When the output voltage restores to the normal range, the power adapter 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
The heat dissipation is provided by the fan of the power module.
Hot swap
The device has power module redundancy. You can hot-swap a power module without interrupting device operation.
PDC400S12-CB FAQ
Q1: Which Huawei high-end devices are compatible with the PDC400S12-CB?
A1: It is mainly compatible with Huawei S5731S series enhanced high-end models (such as H48T4XC-A/H24T4XC-A), S6730-H series core switches, and AR series high-end routers. It is also compatible with Huawei high-end network equipment and industrial control equipment requiring 12V/≤400W power supply.
Q2: What is the core difference between the PDC400S12-CB and the PDC240S12-CN (240W) in the same series?
A2: The former is a high-power, heavy-duty model, with 400W power suitable for high-load/multi-module scenarios, offering higher protection levels and efficiency, and a wider operating temperature range. The latter is a medium-power model, suitable for ordinary load scenarios, and offers better value for money. Both maintain industrial-grade stability.
Q3: What are the advantages of deploying multiple units in parallel in a large data center?
A3: Multiple units connected in parallel can achieve power redundancy and load sharing. The failure of a single unit will not affect the overall power supply. The high power density design reduces the space occupied by the cabinet, and the efficient conversion reduces the overall energy consumption and operation and maintenance costs of the data center.
