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 DETN01L-05 to power low-power analog circuitry in an embedded controller?

Yes, this model is intended for low-power unregulated conversion at 1W with a ±5V output. It is a fit for small analog sections in embedded or industrial electronics where a 4.5~5.5V input and ±5V rails are required.

Is the DETN01L-05 suitable for isolated signal-conditioning stages in industrial equipment?

It can be used for low-power signal-conditioning or interface sections that need ±5V from a 4.5~5.5V input. The 1W rating makes it appropriate for control and measurement circuitry rather than larger loads.

Can this converter be used inside compact automation or IT hardware with limited board space?

Yes, the module is very compact at 15.24 × 10.9 × 7.1 mm and weighs 0.0012 kg. That size is useful in dense embedded, automation, or IT assemblies that need a small 1W DC-DC converter.

Is the DETN01L-05 appropriate for outdoor or harsh-environment use?

The listed operating temperature is -40°C to +90°C, which covers a wide temperature range. No IP rating is provided in the specs, so protection against water or dust exposure is not stated.

How does the DETN01L-05 compare with the other DETN01L models?

Within this series, the DETN01L-05 is rated at 1W with a ±5V output and up to ±100mA output current. The DETN01L-12 is 1W with ±12V output at up to ±42mA, and the DETN01L-15 is 1W with ±15V output at up to ±34mA.
