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 SDM30-48S5 to power 5V embedded systems from a 36~72V source?

Yes, this converter accepts 36~72V input and provides a constant 5V output. With 25W available and up to 5A output current, it fits 5V embedded systems that need more current than a small logic rail. Its 50.8 × 50.8 × 16.0 mm size also makes it practical for compact assemblies.

Is the SDM30-48S5 suitable for industrial USB-class 5V electronics or control peripherals?

It is suitable for 5V electronics when the source is within 36~72V and the total load stays within 25W and 5A. That output level is relevant for control peripherals, communication devices, and embedded boards that are designed around a regulated 5V rail. The constant-voltage output is important for electronics that expect stable 5V input.

Can this model power 5V sensor hubs or single-board computing hardware in automation cabinets?

Yes, that is a reasonable application if the cabinet has a 36~72V supply available. The converter delivers 5V at up to 5A, which is useful for higher-current low-voltage electronics in industrial or automation environments. Buyers should confirm the downstream load remains within the 25W maximum.

How does the SDM30-48S5 compare with the other 36~72V input SDM30 converters?

Among the 36~72V input models, the SDM30-48S3 is 16.5W at 3.3V and 5A, this SDM30-48S5 is 25W at 5V and 5A, the SDM30-48S12 is 30W at 12V and 2.5A, and the SDM30-48S15 is 30W at 15V and 2A. The full family also includes 12V-input versions at 16.5W, 25W, 25.2W, and 25.5W, plus 24V-input versions at 16.5W, 25W, 30W, and 30W. The choice depends on the upstream input range and the exact output voltage and current your load requires.

Is the SDM30-48S5 appropriate for outdoor use or only inside protected equipment?

The operating temperature range is listed as -25°C to +85°C, with the load derated at higher ambient temperatures per the derating curve, so the unit is specified for broad temperature conditions. The provided specs do not show an IP rating, which means there is no stated ingress-protection level for water or dust exposure. In practice, that points to use inside protected housings rather than exposed outdoor mounting.
