Test conditions and notes6
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 5. Heat Sink HS1,HS2,HS3 can not be shorted.
- 6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ
Can I use the PD-25A for a 5V PLC accessory or industrial interface module?
Yes, this dual-output constant voltage model is suitable for 5V industrial interface electronics that operate within 2.1A on the 5V channel; it also has a 12V 1.2A channel, 24.9W total. It is intended for loads that need regulated voltage rather than constant current output.
Is the PD-25A a good choice for embedded controllers or single-board systems that run on 5V?
It can be used for embedded 5V electronics if the 5V load stays within 2.1A rated (2.5A max). The 5V output sits alongside a 12V 1.2A output with 24.9W total, which is appropriate for lower-power digital and embedded assemblies.
Can the PD-25A power a small HMI, logic board, or automation display that needs 5V?
Yes, it provides 5V constant voltage at up to 2.1A rated, plus a 12V 1.2A output. For small automation displays, logic boards, or similar control electronics, the key limits are each channel's current rating and the 24.9W total.
Should the PD-25A be used indoors or outdoors?
The specified operating temperature range is -10°C to +60°C with derating per the derating curve, and no IP rating is provided. That makes it better suited to indoor panels or other protected environments instead of exposed outdoor locations.
What kind of 5V load size is the PD-25A intended for?
This model is intended for 5V constant voltage loads up to 2.1A rated, with a second 12V 1.2A output and 24.9W total. It sits above the PD-25B at 5V 1.2A and below the PD-2505 at 5V 2.5A in rated 5V output current.
