Test conditions and notes6
  1. 1. All parameters NOT specially mentioned are measured at 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 720mm*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. Derating may be needed under low input voltages. Please check the derating curve for more details.
  6. 6. 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-1000H-12 to power a 12V industrial control or automation system from a high-voltage DC bus?

Yes, this converter is built for constant-voltage 12V output from a 72-144V input range. With 720W available and up to 60A output current, it fits higher-power 12V industrial control, automation, and auxiliary DC loads that need substantial current.

Is the SD-1000H-12 a fit for vehicle, rolling stock, or mobile equipment electronics that use a 72-144V source?

It can be a fit where the source voltage falls within the 72-144V input range and the load requires a regulated 12V output. The available 720W and 60A output support heavier 12V electronics than low-power converters.

Can this model support 12V communication, monitoring, or computing loads in an IT or industrial rack?

Yes, the 41mm-high case (295 x 127 x 41mm) and 12V constant-voltage output make it relevant for rack or cabinet-based DC power conversion. Its 720W rating, 60A output, and built-in remote ON/OFF control and remote sense are useful where the 12V load is concentrated in enclosed equipment.

What is the difference between the SD-1000H-12 and the other SD-1000H or SD-1000L versions?

In this output class, SD-1000H-12 and SD-1000L-12 are 720W models with 12V at 60A, SD-1000H-24 and SD-1000L-24 are 960W models with 24V at 40A, and SD-1000H-48 and SD-1000L-48 are 1008W models with 48V at 21A. The H version shown here has a 72-144V input range, while the L versions in this family are listed separately.

Can the SD-1000H-12 be used outdoors or in wide-temperature industrial environments?

The listed operating temperature range is -20°C to +60°C, so the temperature window is intended for industrial environments within that range. No IP rating is shown on this page, so the specs here do not indicate outdoor or washdown protection.
