5V LED board power supply with input-dependent current limits
The South Creative NDC200PS5 is a 5V LED display power supply with a listed output power of 200W. Its maximum current is 40A at 160–240VAC input and 32A at 100–160VAC, making the available mains voltage an important part of load selection.
The design uses natural air cooling and includes input undervoltage, output current limiting and short-circuit protection. Check the module voltage, current demand and cabinet installation against the exact NDC200PS5 specification before replacing an existing supply.

Choosing the operating load
Use the output-current limit for the actual input voltage. The PDF also contains different upper temperatures in its derating notes; do not interpret either as a full-load operating limit. Protection thresholds are separate from the continuous current rating.
Frequently asked questions
How much current does the NDC200PS5 supply at 110V AC?
The specification lists 0–32A for 100–160VAC input. The 0–40A range applies at 160–240VAC. The two bands both include 160VAC as written, so confirm the limit at that exact boundary.
Is this a 5V or 4.5V LED power supply?
The NDC200PS5 specification lists a typical 5V output and a 4.9–5.1V range. Do not substitute it for a 4.5V supply without verifying the LED module’s voltage requirements.
Does the 200W rating apply at every input voltage?
No. The PDF separately lists a 32A limit at 100–160VAC and a 40A limit at 160–240VAC. Follow those limits and the temperature derating information when selecting the load.
What are the efficiency and cooling specifications?
Efficiency is listed as at least 89% at 220VAC and full load. The cooling method is natural air cooling; cabinet airflow and ambient temperature must be considered.
Can I use it above 50°C?
The environmental table lists −30 to +50°C, and separate notes describe derating over 55–80°C and 55–75°C. Confirm the appropriate curve and supplied version before planning high-temperature operation.
