5V power for LED screen cabinets
The South Creative NDE300PS5 is a 5V LED screen power supply with a listed 300W output. It accepts 100–240VAC, but available output current depends on the input: up to 60A at 160–240VAC and up to 50A at 100–160VAC.
For replacement or cabinet design, check the mains voltage, module load and cooling arrangement together. The manufacturer specifies natural air cooling and an aluminum mounting plate for the stated temperature conditions.
NDE300PS5 specifications
Source: the linked V1.0 manufacturer specification dated 31 October 2018. The two input-voltage bands overlap at 160VAC in the document; confirm the applicable limit at that exact voltage.

Load and cooling requirements
The 300W listing does not mean full output is available at every input voltage or ambient temperature. Follow the input-voltage and temperature derating curves in the PDF. The 250 × 200 × 2.0mm figure describes the required aluminum mounting plate, not the power supply housing.
Frequently asked questions
Does the NDE300PS5 deliver 60A on a 110V supply?
No. The specification lists a maximum of 50A for 100–160VAC input and 60A for 160–240VAC input. Both ranges include 160VAC as written; confirm the applicable rating at that boundary before selecting the load.
What is the rated output voltage and power?
The supply is listed as 5V and 300W. Its output-voltage table gives 4.8–5.2V, and available output depends on input voltage and temperature.
Does this LED power supply need a cooling plate?
The environmental conditions require mounting on a 250 × 200 × 2.0mm aluminum plate. The cooling method is natural air cooling. Allow for that plate and airflow when planning the cabinet layout.
Can it operate above 50°C at full load?
The PDF requires derating between 50 and 80°C. Use the manufacturer’s temperature-versus-output curve and specified mounting conditions; do not assume 300W throughout that range.
What does the 90% efficiency figure mean?
The documented efficiency is at least 90% at 220VAC and full load. This test condition should be retained when comparing it with another power supply.
