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-12 in 24V automation equipment to generate low-power ±12V rails?

Yes, it is intended for low-power conversion from a 21-26VAC source to a constant-voltage ±12V output. With 2W total power and 0.08A output current, it is best suited to small analog, control, or interface sections.

Is the DPUN02N-12 a fit for measurement, signal conditioning, or embedded analog circuits?

It can be a fit when the system provides 21-26VAC input and the target circuit needs a low-power ±12V rail. The 2W rating and 0.08A output current make it appropriate for lighter embedded or instrumentation functions rather than higher-current loads.

Can this model be used in compact industrial electronics where board space is limited?

Yes, its 19.6 × 10.2 × 7.2 mm size and 0.0027 kg weight support compact board-level integration. The electrical capability remains 2W with 0.08A output current, so it should be matched to low-power ±12V circuits only.

What are the differences between the DPUN02N-12 and its series siblings?

The DPUN02N-05, DPUN02N-12, and DPUN02N-15 all share a 21-26VAC input range, 2W power, 19.6 × 10.2 × 7.2 mm dimensions, 0.0027 kg weight, and -40°C to +105°C operating range. Their outputs differ as 5V at 200A, 12V at 0.08A, and 15V at 0.07A respectively.

Can the DPUN02N-12 be used in outdoor or severe-temperature environments?

The converter is specified for operation from -40°C to +105°C, so its temperature range is broad. No IP rating is listed, so the product page does not define it for direct outdoor exposure and enclosure protection should determine environmental suitability.
