Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at 24,48,96VDC 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-150B-24 to power a 24V PLC or automation controller from a 19-36V DC system?

Yes, this model is a constant-voltage 24V DC-DC converter with a 19-36V input range. It can deliver up to 6.3A and 151.2W, which fits 24V control and automation loads that stay within those limits.

Is the SD-150B-24 suitable for 24V industrial sensors, relays, and HMI loads on a mobile or battery-based DC bus?

It is designed for 24V output from a 19-36V input range, so it fits DC systems operating in that window. With 6.3A output current and 151.2W available, it is appropriate for grouped 24V control loads that require regulated constant-voltage power.

Can this converter support a 24V embedded computer or communications device in a vehicle or equipment cabinet?

It can be used where the source is 19-36V and the load requires a regulated 24V output. The 151.2W rating and 6.3A output make it a fit for 24V embedded and communications equipment that stays within that power budget.

Is the SD-150B-24 rated for outdoor or washdown environments?

No IP rating is listed for this unit, so it is better suited to protected indoor enclosures rather than exposed outdoor or washdown locations. The published operating temperature range is -10°C to +60°C, with output load derating at higher ambient temperatures (see the derating curve).

How does the SD-150B-24 compare with the other SD-150 series models?

Within the SD-150 group, the 12V models are SD-150B-12, SD-150C-12, and SD-150D-12, each rated at 150W and 12.5A. The 24V models are SD-150B-24, SD-150C-24, and SD-150D-24, each rated at 151.2W and 6.3A. The main difference between B, C, and D versions is the input range: B is 19-36V, C is 36-72V, and D is 72-144V.
