4.5V LED display power supply with input-dependent output
The South Creative NDC250PS4.5 is a 4.5V LED display power supply with a listed output power of 225W. Its synchronous rectification circuit provides efficiency up to 89%, and the housing uses natural air cooling.
Plan the cabinet load around the supply voltage: the model-specific PDF lists 4.5V/40A at 100–180V AC and 4.5V/50A at 180–240V AC. The cover includes 180V in both ranges; consult the input-voltage derating curve or confirm the applicable limit when operating at that boundary.

Selecting a replacement for an LED cabinet
Confirm the module voltage, required current, mains input and cabinet temperature before ordering. Check terminal positions and mounting dimensions against the existing unit. The −40 to +80°C operating range includes a derating requirement from 50°C; it does not guarantee full output at the highest temperature.
Contact LED-Mall with the existing supply label if you need to check replacement suitability.

Frequently asked questions
Can NDC250PS4.5 provide 50A from a 110V supply?
The specification cover lists 4.5V/40A at 100–180V AC input. Its 50A rating is listed for 180–240V AC input, with input-voltage and temperature derating to be checked.
Is this a 4.5V or 5V LED power supply?
The NDC250PS4.5 has a nominal 4.5V DC output and a specified output range of 4.4–4.6V. It should be selected against the LED module’s voltage requirements.
Does it require a cooling fan?
The specified cooling method is natural air cooling. Keep the installation’s ventilation and temperature within the conditions stated in the PDF.
Can it operate at 80°C at full output?
The specification requires derating from 50 to 80°C. Use its temperature derating curve to determine the permitted load for your cabinet temperature.
Where is the NDC250PS4.5 specification PDF?
The original model-specific download link is retained above. It includes input and output limits, protection information and derating curves for checking an installation.
