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-12 to provide 12V for analog or interface circuitry inside industrial equipment?

Yes, this converter is a fit for low-power internal circuits that need an isolated ±12V output from a 10.8~13.2VDC input range. With a 2W rating, it is intended for small electronic sections rather than larger field loads.

Is the DETN02M-12 appropriate for embedded measurement or signal-conditioning modules that need 12V?

It is well suited to embedded designs where a ±12V rail is needed at a modest power level. The 2W output and ±84mA maximum rating make it a better match for compact instrumentation or conditioning stages than power-hungry devices.

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

Yes, its 15.24 × 10.9 × 7.1 mm size and 0.0012 kg weight support dense board layouts and compact assemblies. It is intended for low-power DC-DC conversion in tightly integrated control or monitoring hardware.

Can the DETN02M-12 be used in equipment exposed to wide temperature swings?

The specified operating range is -40°C to +100°C, so it is designed for electronics that may face substantial temperature variation. Because no IP rating is listed, it should be used in protected housings or indoor equipment rather than directly exposed outdoor environments.

What is the difference between the DETN02M-12 and the other models in the same series?

The DETN02M-12 is the ±12V version at 2W and up to ±84mA. The DETN02M-05 is 2W with a ±5V output, and the DETN02M-15 is 2W with a ±15V output at up to ±67mA; all share the same 15.24 × 10.9 × 7.1 mm dimensions, 0.0012 kg weight, and -40°C to +100°C operating range.
