The Huawei PDC240S12-CN is a 240W 12V industrial-grade high-power-density switching power supply module launched by Huawei. Its core advantage is "precise adaptation to high-power scenarios and Huawei's mid-to-high-end equipment"—it has an output power of 240W, an output voltage of 12V with low and stable ripple, and supports a wide input voltage range of 100-240V with a conversion efficiency of ≥88%. It adopts a high-power-density design and industrial-grade components, integrates multiple protections against overvoltage, overcurrent, short circuit, lightning, and surge, covers an operating temperature range of -20℃ to 60℃, supports 24/7 continuous operation, and has an annual failure rate of <0.03%. It is perfectly adapted to scenarios such as Huawei S5731S enhanced/high-end switches, industrial control equipment, and centralized power supply for high-density data centers.

Input undervoltage protection
Stops power output and automatically restores power output after the input voltage becomes normal.
Input overvoltage protection
Stops power output and automatically restores power output after the input voltage becomes normal.
Input overcurrent protection
Stops power output and does not automatically restore power output after the input current becomes normal.
Output current limiting protection
Intermittently provides output and automatically restores normal output after the output current falls within a normal range.
Output overvoltage protection
Intermittently stops output and automatically restores output after the overvoltage condition is removed.
Output short circuit protection
Intermittently provides output and automatically restores normal output after the output short circuit is removed.
Overtemperature protection
When the temperature of the power module reaches a preset threshold, the power module stops power output and will automatically restore power output after the temperature drops back to the normal range.
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.
PDC240S12-CN FAQ
Q1: Which Huawei mid-to-high-end devices are compatible with the PDC240S12-CN?
A1: It is primarily compatible with Huawei S5731S series enhanced switches (such as H48T4XC-A/H24T4XC-A) and S6730 series high-end switches. It is also compatible with Huawei AR series high-end routers and high-power industrial control equipment, supporting Huawei mid-to-high-end network devices requiring 12V/≤240W power supply.
Q2: What is the core difference between the PDC240S12-CN (180W) and the PAC180S12-CN (180W) in the same series?
A2: The former is a high-power model with 240W power, better suited for high-end equipment or multi-module expansion scenarios, offering higher conversion efficiency and protection levels. The latter is a basic power model, suitable for ordinary equipment, and offers better value for money. Both maintain industrial-grade stability.
Q3: How does the high power density design benefit practical use?
A3: High power density means that more power can be provided in the same volume, which can reduce the number of power supply installations, save rack space, reduce cable clutter, and improve the ease of operation and maintenance of the data center/equipment cabinet.
