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 MDD01L-15 for a low-power industrial interface that needs ±15V from a 5V DC source?
Yes, this model is intended for a 4.5~5.5VDC input and provides a fixed ±15V output. With a 1W rating and up to 34mA per output, it fits low-power industrial interface and analog support circuits that need ±15V rails.
Is the MDD01L-15 a fit for embedded instrumentation circuits that run on ±15V?
It is suitable where the embedded instrumentation stage requires a ±15V output and the load stays within the 1W and 34mA-per-output limits. The compact 19.5 × 9.8 × 12.5 mm dimensions also help when instrumentation boards have tight space constraints.
Can this converter be used in automation signal-conditioning hardware that needs ±15V rails?
This model can support low-power signal-conditioning sections that need ±15V and tolerate an unregulated output (±10% load regulation). Its 1W power rating and 4.5~5.5VDC input range align with compact automation electronics rather than heavier-power subsystems.
Is the MDD01L-15 suitable for unheated cabinets or temperature-variable indoor 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 cover wide indoor temperature swings. No IP rating is listed, which means the safer assumption is use inside protected enclosures instead of exposed outdoor locations.
What are the main output options around the MDD01L-15 in the same series?
The 1W MDD01L siblings are ±5V at up to 100mA for MDD01L-05, ±9V at up to 56mA for MDD01L-09, and ±12V at up to 42mA for MDD01L-12. The MDD01L-15 version provides ±15V at up to 34mA per output.
