Test conditions and notes5
- 1. All parameters NOT specially mentioned are measured at 24,48,96VDC input, rated load and 25℃ of ambient temperature.
- 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. Tolerance : includes set up tolerance, line regulation and load regulation.
- 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. 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-150C-12 to step down a 36-72V DC source for a 12V industrial controller?
Yes, this converter is intended for 36-72V input and provides a constant 12V output. It is rated for up to 12.5A and 150W, so it fits 12V control equipment that remains inside those limits.
Is the SD-150C-12 appropriate for 12V embedded or telecom equipment on a 48V-class DC bus?
It is a practical match when the source falls within the 36-72V input range and the load needs regulated 12V DC. The unit can supply up to 12.5A, with a total output rating of 150W.
Can this model power 12V monitoring, signaling, or automation accessories from a higher-voltage DC supply?
Yes, it converts 36-72V input to a constant 12V output for loads that need stable low-voltage DC. Its 150W and 12.5A ratings make it suitable for 12V monitoring and accessory loads within that envelope.
Will the SD-150C-12 work in hot or cold equipment cabinets?
The specified operating temperature range is -10°C to +60°C, with output load derating at higher ambient temperatures (see the derating curve). No IP rating is listed, so it should be used in a protected indoor enclosure rather than an exposed outdoor location.
What are the key differences between the SD-150C-12 and the other SD-150 versions?
The SD-150C-12 is one of three 12V SD-150 models, alongside SD-150B-12 and SD-150D-12, and all three are rated at 150W and 12.5A. The 24V counterparts are SD-150B-24, SD-150C-24, and SD-150D-24, each rated at 151.2W and 6.3A. The B, C, and D versions differ by input range: 19-36V, 36-72V, and 72-144V respectively.
