Input and installation checks
The AC input range starts at 180VAC, so a 115VAC supply is outside this model’s specified range. Keep the fan airflow clear and use the datasheet’s derating curve when assessing the available output at the installation temperature.
Protection functions include short circuit, overload, overvoltage and overtemperature. A power-on LED indicates operation. The original specification download below includes the terminal assignments and mounting drawing.

Frequently Asked Questions
How much power does the NEL-400-5 provide?
It is rated at 5V DC, 80A and 400W. Apply the datasheet’s operating conditions and derating curve when sizing the load.
Can I use it with 110V or 115V AC?
No. The specified AC input range is 180–264VAC.
Is the output voltage adjustable?
Yes. The output adjustment range is 4.5–5.5V. Check the load’s permitted voltage before making an adjustment.
Does the NEL-400-5 use a fan?
Yes. It uses forced-air cooling from a built-in DC fan. Allow space for airflow around the enclosure.
Where can I find the wiring diagram and dimensions?
The specification PDF above includes terminal assignments and the mechanical drawing. The enclosure measures 215 × 115 × 30mm.
