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-150D-12 to derive 12V power from a 72-144V DC system?

Yes, this DC-DC converter is designed for a 72-144V input range and provides constant 12V output. It can supply up to 12.5A, with a total power rating of 150W.

Is the SD-150D-12 suitable for 12V industrial control or monitoring electronics on a high-voltage DC bus?

It is intended for applications where the source voltage falls between 72V and 144V and the load requires regulated 12V DC. The 12.5A output current and 150W capacity fit 12V control and monitoring loads within that range.

Can this model power 12V embedded hardware in transportation or automation equipment with higher DC input voltage?

Yes, it is a constant-voltage 12V converter for 72-144V input systems. It supports up to 150W output and up to 12.5A for 12V embedded hardware that matches those electrical limits.

Does the SD-150D-12 have an outdoor environmental rating?

No IP rating is listed in the provided specifications, so it should be used in a protected indoor enclosure instead of an exposed outdoor environment. Its specified operating temperature range is -10°C to +60°C, with output load derating at higher ambient temperatures (see the derating curve).

Which SD-150 model should I compare this with in the same series?

For 12V output, the direct siblings are SD-150B-12, SD-150C-12, and SD-150D-12, and all are rated at 150W and 12.5A. Their difference is input range: 19-36V for B, 36-72V for C, and 72-144V for D. The 24V variants are SD-150B-24, SD-150C-24, and SD-150D-24, each rated at 151.2W and 6.3A.
