NDB300PS5 LED video screen power supply
The South Creative NDB300PS5 supplies nominal 5V DC power for LED displays. Its 300W rating must be considered together with the AC input voltage: the specification lists a 60A output limit at 160–240VAC and a 50A limit at 100–160VAC.
When choosing a replacement, check the full model number, DC voltage, cabinet load and terminal arrangement. A 300W label alone is not sufficient to confirm suitability for the installation.

The PDF includes 160VAC in both current-rating bands. Confirm the applicable limit at that boundary before designing for maximum load. Its environmental table specifies −30°C to 50°C and notes derated use from 50°C to 80°C; consult the derating curve for the actual installation.
Frequently Asked Questions
Does the NDB300PS5 provide 60A on a 110V supply?
No. The specification lists up to 50A for the 100–160VAC input band. The 60A rating applies to the stated 160–240VAC band.
Is the NDB300PS5 a 5V or 12V power supply?
It is a nominal 5V DC power supply. The specified output voltage range is 4.8–5.2V; it is not a 12V supply.
Can I use the full 300W rating at any temperature?
No. Output selection must follow both the input-voltage limits and the temperature derating information in the specification. Check the cabinet environment before selecting the load.
What protection functions does this model have?
The manufacturer’s specification lists input undervoltage protection, output current limiting and output short-circuit protection.
Where can I find the NDB300PS5 datasheet?
The original specification PDF is linked below. Use it to check the electrical ratings, installation requirements and mechanical information before replacing an existing supply.
