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-15C-12 for 12V industrial control electronics in a higher-voltage system?
It can fit low-power 12V control electronics when the source is within the listed 36-72VDC range and the load stays within 15W and 1.25A. Because it is a constant voltage 12V converter, it is better suited to fixed-voltage electronics than to larger 12V loads above its rated output.
Is the PSD-15C-12 suitable for instrumentation or monitoring devices that need 12V power?
This model can suit compact instrumentation, sensing, or monitoring electronics that require regulated 12V and modest power demand. Its 15W rating and 1.25A output keep it in the low-power category for embedded and industrial equipment.
Can the PSD-15C-12 be used inside telecom or network equipment cabinets for auxiliary 12V loads?
It can serve low-power 12V auxiliary electronics if the available input is within 36-72VDC and the total load remains within 15W and 1.25A. The datasheet's 2.0KVAC input-to-output withstand voltage is also relevant for cabinet-based IT and control applications.
Would the PSD-15C-12 work for embedded automation modules in a compact enclosure?
The 94.0 x 49.0 x 25.0 mm dimensions and 0.081 kg weight make it practical for compact enclosures. Its constant voltage 12V output is appropriate for low-power automation modules and electronics that do not exceed 1.25A.
How does the PSD-15C-12 compare with the 5V and 24V versions in the same family?
The PSD-15C-12 is rated at 15W, 12V, and 1.25A. In the same PSD-15C family, the 5V version is rated at 15W and 3A, while the 24V version is rated at 14.4W and 0.6A.
Can the PSD-15C-12 be used outdoors or in dusty industrial areas?
The listed operating temperature is -10C to +60C, so the temperature condition needs to stay inside that range. No IP rating is provided in the specs, which means this product data does not confirm outdoor or dust-tight use.
