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 DETN02N-12 to supply 12V signal-conditioning or interface electronics in industrial controls?

Yes, it is suited to low-power ±12V control, signal, or interface circuits that stay within 2W. It is specified for a 21.6~26.4VDC input and operates from -40°C to +100°C (with derating at high ambient, per the derating curve).

Is this converter a good fit for embedded analog circuits that require 12V output?

It can be used where embedded analog or mixed-signal electronics need an isolated ±12V output and the load does not exceed ±84mA. As an unregulated converter (load regulation ±8%), it suits circuitry that tolerates some output change with load.

Can the DETN02N-12 be used in compact automation modules or instrumentation boards?

Its 15.24 × 10.9 × 7.1 mm package and 0.0012 kg weight make it suitable for compact modules and densely packed boards. It is a practical option for instrumentation or automation electronics that need ±12V output within a 2W budget.

Is the DETN02N-12 intended for indoor-only use, or can it handle wider temperature conditions?

The converter is rated for operation from -40°C to +100°C, so it can handle a broad temperature range in equipment design. Because no IP rating is listed, the specs do not establish outdoor exposure or water-ingress protection.

How does the DETN02N-12 compare with the other DETN02N 2W models?

The series shares the same 2W power class but differs by output rating. DETN02N-05 is ±5V at up to ±200mA, DETN02N-12 is ±12V at up to ±84mA, and DETN02N-15 is ±15V at up to ±67mA.
