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 DETN01N-05 to power 5V logic in a 24V industrial control panel?

It can fit low-power 5V logic applications when the source feeding the converter stays within the 21.6~26.4Vdc input range. The output is an unregulated ±5V with 1W rated power, so it is best suited to small control, monitoring, or interface circuits rather than larger loads.

Is the DETN01N-05 suitable for embedded monitoring or sensing electronics inside industrial equipment?

Yes, it is sized for low-power embedded electronics that need ±5V rails from a nominal 24V input range of 21.6~26.4Vdc. Its compact 15.24 × 10.9 × 7.1 mm package also makes it easier to use where board space is limited.

Can this 1W converter be used for low-power automation interface modules?

It is appropriate for low-power automation interfaces that need a ±5V output and only require 1W of power. Buyers should match the load to the listed ±5V output and 1W rating instead of using it for higher-power automation hardware.

How does the DETN01N-05 compare with the DETN01N-12 and DETN01N-15?

All three models are 1W DC-DC converters with the same 21.6~26.4Vdc input range, 15.24 × 10.9 × 7.1 mm dimensions, -40°C to +90°C operating range, and 3-year warranty. The difference is the output: DETN01N-05 is ±5V at up to ±100mA, DETN01N-12 is ±12V at up to ±42mA, and DETN01N-15 is ±15V at up to ±34mA.

Is the DETN01N-05 suitable for outdoor or harsh-temperature environments?

The listed operating temperature range is -40°C to +90°C, so the temperature specification is broad. No IP rating is provided in the listed specs, so outdoor exposure or wet-location suitability is not defined by this product data.
