Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at 12,24,48,96VDC 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-100B-12 to power a 12V PLC or industrial control panel from a 19-36V source?

Yes, this model is a constant voltage DC-DC converter with a 12V output rated at 8.5A and 102W. It fits control and automation loads that need regulated 12V power when the available input is within the 19-36V range.

Is the SD-100B-12 suitable for 12V embedded computers, HMIs, or communications hardware in mobile equipment?

It can be a fit for 12V embedded and IT hardware that needs constant voltage power and stays within 8.5A and 102W. The 2:1 wide input range of 19-36V is useful where the source is not fixed at a single input value.

Can the SD-100B-12 be used for 12V automation accessories such as relays, small actuators, or monitoring devices?

This converter is suited to 12V automation loads that require constant voltage and draw no more than 8.5A. Its 102W rating makes it more appropriate for moderate 12V panel loads than for higher-current systems.

Is the SD-100B-12 suitable for outdoor or harsh-environment use?

The listed specs give an operating temperature range of -10°C to +60°C for the SD-100B series, but no IP rating is provided. That means outdoor or washdown suitability is not defined by the stated specs, so it is better matched to protected indoor enclosures within that temperature range.

How does the SD-100B-12 compare with other SD-100 series output options?

Within the SD-100 group, the 12V versions include SD-100A-12, SD-100B-12, SD-100C-12, and SD-100D-12, each rated at 102W and 8.5A. The 24V versions include SD-100A-24, SD-100B-24, SD-100C-24, and SD-100D-24 at 100.8W and 4.2A, while the 5V versions include SD-100A-5, SD-100B-5, SD-100C-5, and SD-100D-5 at 100W and 18A.
