Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at normal input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 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. 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 SD-15A-24 to run a small 24V industrial sensor or transmitter from a 9.2-18VDC input source?

Yes, if the device needs a constant 24V output and draws no more than 0.625A. This converter provides 15W total and accepts a 9.2-18VDC input range, so it is intended for low-power 24V industrial or embedded loads.

Is the SD-15A-24 a good choice for a compact 24V automation accessory in a tight enclosure?

It is designed for small low-power 24V loads, with a 78.0 × 51.0 × 28.0 mm housing and 0.18 kg weight. The output is limited to 24V at 0.625A, so it fits light auxiliary devices rather than higher-current 24V equipment.

Can this model power a 24V embedded or control module from a low-voltage source?

It can when the source stays within the 9.2-18VDC input range and the module requires constant voltage output. The 15W capacity makes it suitable for smaller 24V control or embedded electronics that remain under 0.625A.

Is the SD-15A-24 suitable for outdoor installations or wide temperature swings?

The specified operating temperature range is -10°C to +60°C, with output derating at higher temperatures per the derating curve. However, no IP rating is provided in the listed specs, so the product data does not state outdoor or weather-exposed suitability.

How does the SD-15A-24 compare with the other SD-15A output options?

The SD-15A family includes SD-15A-5 at 15W, 5V, 3A; SD-15A-12 at 15W, 12V, 1.25A; and SD-15A-24 at 15W, 24V, 0.625A. Each version uses the same 9.2-18VDC input range, constant voltage mode, -10°C to +60°C operating temperature (with derating), 78 × 51 × 28 mm dimensions, 0.18 kg weight, and EAC TP TC 004 approval.
