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-15B-12 for 12V industrial instrumentation or panel devices?
Yes, it provides constant 12V output with a 15W rating and up to 1.25A output current. That makes it suitable for 12V instrumentation, panel devices, and control accessories that stay within those limits.
Is the PSD-15B-12 suitable for a control cabinet with an 18-36VDC source?
Yes, this model is specified for 18-36VDC input and converts that to regulated 12V output. It is appropriate for cabinet-based automation loads that need 12V constant-voltage power up to 15W.
Can this converter support small 12V embedded or monitoring electronics?
It can support 12V embedded and monitoring electronics when the total load remains within 1.25A and 15W. The 94.0 x 49.0 x 25.0 mm dimensions and 0.081 kg weight are also helpful where space is limited.
Can the PSD-15B-12 be used in outdoor or unprotected locations?
The stated operating temperature is -10°C to +60°C, but no IP rating is listed on the datasheet. That means the temperature window is defined, while environmental sealing for outdoor exposure is not.
How does the PSD-15B-12 fit within the broader PSD converter lineup?
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-15B-12 is the 12V, 1.25A, 15W version for 18-36VDC input.
