Test conditions and notes5
- 1.All parameters NOT specially mentioned are measured at normal input,rated load and 25℃ of ambient temperature.
- 2.Ripple & noise are measued at 20 MHz of bandwidth by using a 12inch twisted pair-wire termined with a 0.1μF & 47μF 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 230mm*230mm 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.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 PSD-15A-12 for a 12V industrial sensor or control module?
Yes, it is a constant-voltage 12V converter rated for 15W with up to 1.25A output. That makes it suitable for 12V industrial sensors, alarm modules, and control accessories that stay within the unit's rated 15W output.
Is the PSD-15A-12 a fit for embedded 12V electronics in a compact machine enclosure?
It can be a good fit for embedded 12V electronics when the load requires constant 12V power and remains within 1.25A. Its 94.0 x 49.0 x 25.0 mm size and 0.081 kg weight also suit space-constrained control housings.
Can this converter power a small 12V automation accessory from a 9.2-18VDC source?
Yes, this model is designed for a 9.2-18VDC input range and provides a regulated 12V output. It is appropriate for small 12V automation accessories when total demand stays within 15W.
Is the PSD-15A-12 suitable for outdoor or harsh-environment use?
The provided specs list an operating temperature of -10°C to +60°C, but no IP rating is given. That means the temperature range is defined, but outdoor or washdown suitability is not stated and would require additional protection if the environment demands it.
How does the PSD-15A-12 compare with other Mean Well PSD series options?
The PSD-15 series offers 5V 3A (15W), 12V 1.25A (15W) and 24V 0.6A (14.4W) outputs, each with A (9.2-18VDC), B (18-36VDC) or C (36-72VDC) input. The PSD-15A-12 specifically sits in the 15W, 12V, 1.25A group for 9.2-18VDC input.
