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 DETN02L-12 for ±12V analog sections in industrial measurement or control equipment?

Yes, this model provides an isolated ±12V output and is rated at 2W. That makes it suitable for low-power analog, measurement, or interface sections in industrial electronics that operate from a 4.5~5.5VDC input range.

Is the DETN02L-12 suitable for embedded systems that need a small ±12V auxiliary rail?

It can be a fit when the embedded design needs a low-power ±12V rail and stays within the 2W and ±84mA output rating. The package is also compact at 15.24 × 10.9 × 7.1 mm, which helps in tightly packed assemblies.

Can this converter support low-power op-amp or interface circuitry in automation products?

For low-power circuitry that requires a ±12V output, the DETN02L-12 is aligned with that use case. Its 2W power level and ±84mA maximum output rating indicate it is for auxiliary or signal-level sections rather than larger loads.

Would the DETN02L-12 work in compact telecom or IT boards that need ±12V from a low input range?

It is designed for a 4.5~5.5VDC input range and delivers ±12V output at 2W, which fits low-power support rails in compact electronic equipment. Its 0.0012 kg weight and small footprint are useful where mechanical constraints matter.

Is the DETN02L-12 rated for cold or hot equipment environments?

The specified operating temperature is -40°C to +100°C, so the converter is rated for very low and very high internal equipment temperatures. No IP rating is listed, so the specs cover temperature capability but do not confirm outdoor or washdown suitability.

What is the difference between the DETN02L-12 and the other DETN02L versions?

The family keeps the same 2W series format but changes the output rating by model. The DETN02L-05 is ±5V at up to ±200mA, the DETN02L-12 is ±12V at up to ±84mA, and the DETN02L-15 is ±15V at up to ±67mA. Selection within the series comes down to the required output voltage and current.
