Test conditions and notes5
- 1.All parameters are specified at normal input(L:5Vdc, M:12Vdc, N:24Vdc), rated load, 25℃ 70% RH ambient.
- 2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.
- 3.Line regulation is measured from low line to high line at rated load.
- 4.Load regulation is measured from 20% to 100% rated load.
- 5.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)

FAQ
Can I use the DPUN02N-05 in a 24V control cabinet to power low-voltage embedded electronics?
Yes, it is designed for systems with a 21.6-26.4VDC input range and a constant-voltage ±5V output. With a 2W power rating, it is better suited to low-power embedded or interface electronics than to larger control loads.
Is the DPUN02N-05 suitable for low-power industrial monitoring or logic circuits that need 5V?
It can be used where the source side is within 21.6-26.4VDC and the circuit needs a regulated ±5V rail. The product is rated at 2W, so it fits smaller monitoring, signal, or logic sections rather than high-demand subsystems.
Can this converter be used for compact automation boards in 24V-class equipment?
Yes, the 19.6 × 7.2 × 10.2 mm package is suitable for compact board-level designs inside 21.6-26.4VDC equipment. Its 2W rating and listed ±200mA output current mean the electrical selection should be checked directly against the load requirement shown in your design data.
How does the DPUN02N-05 compare with the other DPUN02N models?
All DPUN02N models use a 21.6-26.4VDC input, deliver 2W, measure 19.6 × 7.2 × 10.2 mm, weigh 2.7g, and operate from -40°C to +105°C. Within the series, the DPUN02N-05 is ±5V with ±200mA output current, the DPUN02N-12 is ±12V with ±83mA, and the DPUN02N-15 is ±15V with ±67mA.
Is the DPUN02N-05 rated for outdoor use or high-temperature enclosures?
The published temperature range is -40°C to +105°C, which supports demanding thermal conditions. No IP rating is shown, so the page does not identify it as outdoor rated and exposed use should rely on the protection of the host enclosure.
