Test conditions and notes7
  1. 1. All parameters NOT specially mentioned are measured at 12,24,48VDC 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. Short circuit not more than 60 second.
  5. 5. DC source wires ≧5cm, an input external al capacitor 47 ~ 100uF is required.
  6. 6. 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 )
  7. 7. 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 SDM30-24S5 to power 5V embedded or automation electronics from a 24V-class DC source?

Yes, if the source is within the specified 18-36VDC input range and the load needs constant 5V within 25W and 5A. That makes it suitable for 5V embedded and automation electronics that need a regulated low-voltage rail from that input range.

Is the SDM30-24S5 suitable for 5V control logic or industrial communication modules?

It can be used for 5V control and communications electronics when the total output stays within 5A and 25W. The model is rated for constant-voltage 5V output, which is the relevant requirement for those types of loads.

Can this converter support 5V loads that need more current than smaller logic supplies provide?

Yes, this version provides up to 5A at 5V, so it suits higher-current 5V loads within a 25W envelope. Buyers should confirm that the combined demand of the target electronics does not exceed either of those published limits.

How well does the SDM30-24S5 handle temperature extremes, and is it outdoor rated?

The operating temperature range is listed as -25°C to +85°C, with load derating at higher ambient temperatures per the derating curve, which covers a broad temperature span. The provided specs do not state an IP rating, so outdoor or wet-environment suitability is not established from this product data alone.

How does the SDM30-24S5 compare with the rest of the SDM30 series?

The sibling lineup includes 3.3V models at 16.5W and 5A, 5V models at 25W and 5A, 12V models at 25.2W and 2.1A or 30W at 2.5A, and 15V models at 25.5W and 1.7A or 30W at 2A. It also spans 9.2-18V, 18-36V, and 36-72V input groups, and the SDM30-24S5 is the 18-36V input, 5V output, 25W, 5A variant.
