Product introduction:
This Server-Grade Power Supply Board features advanced interleaved PFC and LLC resonant topology, delivering up to 91% efficiency (at 240VAC full load) across 100-240VAC input range. Certified to UL62368 and EN62368 standards, its dual isolated outputs provide 54V/9.25A (500W) and 12V/5A (60W) simultaneously, with total 561W output for demanding industrial applications.
The rugged 100×240×37mm metal housing incorporates military-grade cooling with dual ball-bearing fans and copper heat pipes, maintaining full load operation from -20℃ to 45℃. With 5G vibration/20G shock resistance and >100,000 hours MTBF, it offers OVP/OCP/SCP/OTP protections (auto-recovery). Optimized EMI meets CISPR32 Class B with <150mVp-p ripple, ideal for medical imaging and 5G base stations.
The board utilizes AEC-Q200 certified components with 100% burn-in testing, ensuring stable output even at 85℃ ambient. Its digital control achieves ±0.5% voltage regulation, while PMBus 1.3 interface enables remote monitoring. Passing 2000m altitude and 85% humidity tests, it guarantees reliable power for edge computing and outdoor telecom equipment.

Frequently Asked Questions
What is the total maximum output power of this dual-output power supply?
+
-
The total maximum power is approximately 561W, calculated as (54V * 9.5A) + (12V * 4A). The input power rating of 675W max ensures it can reliably support this output.
Is this power supply suitable for global use?
+
-
Yes. With a wide input voltage range of 90Vac to 264Vac, it is designed to operate from standard wall outlets in most countries around the world without needing a manual selector.
What cooling is required for this unit?
+
-
This is a force-air-cooled unit. It requires a minimum airflow of 30 CFM directed from the output end to the input end for proper thermal management and to achieve the full power rating across the operating temperature range.
How stable are the output voltages under varying line and load conditions?
+
-
The outputs are very stable.
* Line Regulation: ±2% for both outputs (for changes in input voltage).
* Load Regulation: ±3% for both outputs (for changes in output current from min to max).
What is the typical application for these specific voltage outputs (54V and 12V)?
+
-
This combination is commonly used in systems requiring a high-voltage bus for motor drives (e.g., 54V for industrial/robotic actuators) and a lower voltage for control logic, sensors, and cooling fans (12V). It is ideal for industrial automation, networking equipment, and test & measurement devices.
