400W power supply for 5V LED video walls
The Rong-Electric MNL400PC5S is a 5V, 80A LED display power supply rated at 400W. It accepts a rated 100–240VAC input and is documented with input undervoltage, output current limiting and short-circuit protection.
Its stated efficiency of at least 90% applies at 220VAC, full load and room temperature. Cabinet cooling is a separate selection requirement, particularly when ambient temperature exceeds 50°C.

Cooling requirements for LED cabinets
The environmental table lists −30 to +50°C and refers to the temperature derating curve. For full-load operation at 50–60°C ambient, the manufacturer requires close contact with a 200 × 300 × 3mm heat sink. This is an additional cooling requirement, not the housing size.
Before installation, compare the terminal layout and mounting drawing with the cabinet and confirm the LED modules’ required voltage and total load.
Frequently asked questions
What is the output of the MNL400PC5S?
The manufacturer lists a +5.0V rated output, 0–80A output current and 400W output power. The output-voltage range is 4.9–5.1V.
Is it suitable for 110V and 230V AC mains?
Both voltages fall within the rated 100–240VAC input range. The PDF separately lists a wider 90–264VAC operating range. Check the installation and loading conditions in the specification before use.
Can it operate at full load in a 60°C cabinet?
The PDF states that full-load operation at 50–60°C ambient requires close contact with a 200 × 300 × 3mm heat sink for additional cooling. Follow the temperature derating curve and do not assume full output without that cooling arrangement.
What does the 90% efficiency rating refer to?
The documented figure is ≥90% at 220VAC, full load and room temperature. It should not be treated as a measured result at every input voltage, load or temperature.
Can I replace another 5V 80A supply with the MNL400PC5S?
Check the input range, exact output requirements, terminal layout, mounting dimensions and cooling provisions first. Matching 5V and 80A ratings alone does not establish that two supplies fit or operate interchangeably.
