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.Patient leakage current(2μA max.) and reinforced isolation is based on a 250VAC, 50/60Hz system input voltage.
6.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)

FAQ

Can I use the MDD02N-15 in a 24V automation system that needs isolated +/-15V for analog circuitry?

It is intended for 24V-class systems operating within the 21.6~26.4Vdc input range and needing an unregulated +/-15V output. With 2W total power and up to 67mA per output, it is best for low-power analog or interface sections rather than higher-current loads.

Is the MDD02N-15 a good fit for compact embedded boards that require a small +/-15V rail?

This converter is built for space-constrained designs, with dimensions of 19.5 x 9.8 x 12.5 mm and a weight of 0.0042 kg. It suits embedded or industrial boards that need a small unregulated +/-15V auxiliary supply within the 2W rating.

Can the MDD02N-15 support low-power measurement or amplifier sections in industrial electronics?

Yes, when the circuit needs +/-15V and remains within the converter's 2W and 67mA-per-output limits. That makes it more appropriate for low-power signal paths, measurement stages, or interface electronics than for heavier subsystem loads.

Does the MDD02N-15 handle harsh temperature conditions in enclosed equipment?

Its specified operating range is -40°C to +85°C, which supports use in equipment exposed to broad industrial temperature variation. The listed specs do not provide an IP rating, so environmental sealing has to come from the enclosure rather than the converter itself.

What is the difference between the MDD02N-15 and the other MDD02N versions?

All MDD02N models share the 2W power class and 21.6~26.4V input while changing output ratings: MDD02N-05 is +/-5V, +/-20~200mA; MDD02N-09 is +/-9V, +/-12~111mA; MDD02N-12 is +/-12V, +/-9~83mA; and MDD02N-15 is +/-15V, +/-7~67mA. The MDD02N-15 is the +/-15V option.
