4.5V enclosed power supply for LED sign panels
The South Creative NDC500PS4.5 supplies 4.5V DC to LED display modules. It includes PFC and natural air cooling in a compact enclosed housing. For replacement projects, the key selection point is the input-dependent output rating: the model-specific specification lists 80A at 100–180V AC and 100A at 181–240V AC.
Check the mains supply and cabinet temperature before sizing the load. The maximum current is not available across every input voltage or operating temperature.

Choosing a replacement
Match the LED module voltage, required current, mounting points and terminal arrangement. The specification describes input undervoltage, output overcurrent and output short-circuit protection. Keep space around the housing for natural air cooling and allow for the temperature derating stated in the document.
For a fit check, send LED-Mall the existing supply model and module requirements.

Frequently asked questions
Does the NDC500PS4.5 deliver 100A on a 110V supply?
No. The model-specific specification lists 4.5V/80A for 100–180V AC input and 4.5V/100A for 181–240V AC input. Use the input-voltage derating curve when sizing the load.
What is the DC output voltage?
The nominal output is 4.5V DC, with a specified range of 4.4–4.6V. Match this to the LED module requirements before connecting the display.
Can this power supply operate at 80°C?
The specification lists an operating range of −40 to +80°C, with derating required between 50 and 80°C. This does not mean full-load output is available at 80°C.
Does the NDC500PS4.5 have PFC?
Yes. Its specified power factor is at least 0.95 at 220V AC and full load. That condition matters when comparing it with another power supply.
Where can I download the NDC500PS4.5 specification?
Use the specification download link above for the model-specific PDF. It includes electrical limits, environmental conditions and derating information needed for selection and installation.
