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-05 to power 5V logic rails in an embedded controller or industrial I/O board?

It is intended for isolated ±5V output applications and is rated at 2W. That makes it a fit for low-power embedded, control, or interface circuits that need ±5V output from a 4.5~5.5VDC input range. Its operating range of -40°C to +100°C (with derating at high ambient, per the derating curve) also suits equipment that sees wide internal temperature swings.

Is this DC-DC converter appropriate for low-power analog signal conditioning in automation equipment?

Yes, the DETN02L-05 provides ±5V output in a 2W package, which is commonly aligned with low-power analog support circuitry. The compact 15.24 × 10.9 × 7.1 mm size also makes it practical where board space is tight inside automation hardware.

Can the DETN02L-05 be used in compact IT or communications hardware with limited PCB space?

It is built for compact layouts, with dimensions of 15.24 × 10.9 × 7.1 mm and a weight of 0.0012 kg. For low-power sections that need ±5V output and stay within the 2W rating, it fits dense embedded or communications assemblies well.

Is the DETN02L-05 a good match for isolated support power in small instrumentation modules?

For small instrumentation sections that need ±5V, this model is sized for that role with a 2W rating. Its 3KVDC input-output isolation and EAC TP TC 020/2011 approval can also matter in regulated industrial and electronic equipment.

Can I use this converter outdoors or in harsh environments?

The listed operating temperature is -40°C to +100°C, so the temperature range is broad. However, no IP rating is provided in the product data, so the specs do not establish outdoor exposure or water and dust resistance.

How does the DETN02L-05 compare with the other DETN02L 2W models?

All three listed siblings are 2W parts in the same series. 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. If you are choosing within the family, the main difference is the output voltage and corresponding output current.
