300W LED video screen power supply
The South Creative NDB300PS5, also listed as Nandian NDB300PS5, supplies a typical 5V DC output for LED displays. Its 300W specification is accompanied by input-dependent current limits: 60A maximum at 160–240VAC and 50A maximum at 100–160VAC.
For cabinet load planning, start with the actual mains voltage and operating temperature. Natural air cooling and the manufacturer’s derating curve determine the installation conditions to check alongside the module load.

Replacement checks
Match the LED modules’ voltage and current requirements, then compare the terminal layout and mounting drawing with the existing cabinet. The listed protection functions do not increase the continuous output rating, and similar model names do not establish mechanical interchangeability.
Frequently asked questions
Is NDB300PS5 a 5V 60A LED screen power supply?
Yes. The specification lists 5V typical output and up to 60A at 160–240VAC input. At 100–160VAC input, the maximum current is 50A.
Can it provide 300W from a 110V AC input?
Do not select the load on the 300W model rating alone. At 110VAC, the applicable output-current band is 0–50A. The 0–60A band is specified for 160–240VAC.
What happens at exactly 160V AC input?
The PDF writes the current bands as 100–160VAC and 160–240VAC, so they overlap at 160VAC. Confirm the applicable limit at that boundary before sizing a load.
Does it need derating in a hot LED cabinet?
Yes. The environmental table lists −30 to +50°C and requires derating between 50 and 80°C. Use the temperature-versus-output curve rather than assuming full output throughout the range.
