5V 40A supply for LED display cabinets
The South Creative NDD200PS5 is a 200W LED display power supply with a typical 5V DC output and a 0–40A output-current range. It uses natural air cooling and has a rated AC input of 100–240V.
The manufacturer documents input undervoltage, output current limiting and short-circuit protection. When replacing an existing supply, match the output voltage, load, terminal arrangement and mounting dimensions before installation.

Temperature and protection limits
The PDF’s temperature table and derating notes do not give one consistent high-temperature range. Check the applicable derating curve before choosing the cabinet load. Current-limit and short-circuit recovery functions are protective features and do not raise the documented 40A output rating.
Frequently asked questions
What is the NDD200PS5 output rating?
The manufacturer lists a typical 5V DC output, a 0–40A output-current range and 200W output power. The voltage range in the table is 4.9–5.1V.
Can I use this supply with 110V or 230V AC?
Both voltages are within the rated 100–240VAC input range. The wider operating range is listed separately as 90–264VAC. Follow the applicable loading and temperature conditions in the specification.
What efficiency and power factor are specified?
At 220VAC and full load, the PDF lists efficiency of at least 89% and a power factor of at least 0.95. These figures should not be treated as test results for every operating condition.
Can the NDD200PS5 deliver 60A continuously?
No. Its output-current rating is 0–40A. The separate 44–60A current-limit protection range is a protection threshold, not a continuous output rating.
What temperature limit should I use for cabinet design?
The environmental table lists −30 to +50°C, while the notes describe derating over 55–80°C and 55–75°C. Because those entries differ, confirm the applicable curve and supplied version before designing for high-temperature operation.
