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 DPUN02M-12 in a 12V industrial control panel to create low-power ±12V rails?

Yes, it is intended for low-power constant-voltage conversion in systems with a 10.8~13.2VDC input range and a ±12V output. With 2W total power and ±83mA output current, it fits small analog, signal, or control subcircuits rather than higher-load equipment.

Is the DPUN02M-12 a good fit for embedded analog or sensor interface circuits that need ±12V?

It can be a fit when the source side is within 10.8~13.2VDC and the load only needs a low-power ±12V rail. The 2W rating and ±83mA output current make it better suited to compact embedded or measurement-related circuitry than to larger control loads.

Can this converter support low-power automation electronics that need bipolar 12V rails?

Yes, for low-power automation electronics that operate from a 10.8~13.2VDC source and need constant-voltage ±12V output. Its 2W capacity and 19.6 × 7.2 × 10.2 mm size make it appropriate for compact board-level use where current demand stays within ±83mA.

How does the DPUN02M-12 compare with the other DPUN02M models?

All three DPUN02M models are 2W converters with the same 19.6 × 7.2 × 10.2 mm dimensions, 2.7g weight, and -40°C to +105°C operating range. In this group, the DPUN02M-05 is ±5V with ±200mA output current, the DPUN02M-12 is ±12V with ±83mA, and the DPUN02M-15 is ±15V with ±67mA.

Is the DPUN02M-12 suitable for outdoor or high-temperature equipment?

The listed operating temperature is -40°C to +105°C, which supports a wide temperature range. No IP rating is provided, so the product page does not define it as outdoor rated and exposed use should depend on the protection of the final enclosure.
