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 MDD01N-15 to generate a low-power plus/minus 15V rail from a 24V-class source?
Yes, this converter is designed for applications with a 21.6~26.4VDC input that need a fixed ±15V output. Its 1W rating and up to 34mA per output make it suitable for small analog or interface sections rather than larger devices.
Is the MDD01N-15 appropriate for industrial analog conditioning or instrumentation circuits?
It is a fit for low-power instrumentation, conditioning, or signal-interface circuits that need ±15V from a 24V-class supply. The available output current is up to 34mA per output, so it is intended for light auxiliary loads.
Would this model work in embedded test, control, or measurement electronics with tight board space?
Yes, the package is only 19.5 × 9.8 × 12.5 mm and weighs 0.0042 kg, which helps in compact embedded assemblies. It is best used where the load fits within the 1W output capability and requires ±15V.
How does the MDD01N-15 differ from the other MDD01N converters in the same series?
The siblings are MDD01N-05 at ±5V up to 100mA, MDD01N-09 at ±9V up to 56mA, and MDD01N-12 at ±12V up to 42mA. The MDD01N-15 itself is the ±15V version with up to 34mA per output, and all listed units are 1W models.
Is the MDD01N-15 suitable for outdoor use or wide-temperature industrial enclosures?
The specified operating temperature range is -40°C to +85°C (with load derating at higher temperatures, see the derating curve), so it can support equipment used in broad temperature conditions. The provided specs do not include an IP rating, so exposed outdoor, wet, or washdown use is not explicitly defined.
