Test conditions and notes6

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 10% 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)
6.An external input filter capacitor is required if the module has to meet BS EN/EN61000-4-4, BS EN/EN61000-4-5. The filter capacitor Power Mate suggest: 470μF/100V.

FAQ

Can I use the DETN02M-05 to generate a 5V rail inside a 12V industrial control board?

Yes, this model is intended for low-power isolated DC-DC conversion in equipment that needs a ±5V output from a 10.8~13.2VDC input range. Its 2W rating makes it a fit for small control, interface, and signal-conditioning sections rather than larger loads.

Is the DETN02M-05 suitable for embedded electronics in a vehicle or battery-based 12V system?

It can fit embedded designs on a nominal 12V source as long as the supply stays within the listed 10.8~13.2VDC input range (surge 16VDC for 100ms max.). The ±5V output and 2W power level make it better suited to compact electronic circuits than higher-power subsystems.

Can this converter be used for low-power automation sensors or logic circuits that need 5V?

Yes, it is appropriate where a ±5V output is needed in a small automation or monitoring circuit. The 2W capacity and compact 15.24 × 10.9 × 7.1 mm package are aligned with tightly packed, low-power designs.

Is the DETN02M-05 suitable for outdoor or harsh exposed environments?

The operating temperature range is -40°C to +100°C, which supports use across a wide temperature span. However, no IP rating is listed, so it is better treated as a board-level part for protected indoor equipment or enclosed systems rather than exposed outdoor use.

How does the DETN02M-05 compare with the other DETN02M series options?

Within this series, the DETN02M-05 is rated 2W with a ±5V output (up to ±200mA), while the DETN02M-12 is 2W with ±12V at up to ±84mA and the DETN02M-15 is 2W with ±15V at up to ±67mA. All three share the same 15.24 × 10.9 × 7.1 mm dimensions, 0.0012 kg weight, and -40°C to +100°C operating temperature range.
