Test conditions and notes6
- 1. All parameters NOT specially mentioned are measured at 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 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. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 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-24 for 24V PLC, relay, and automation equipment?
Yes, this model provides a constant-voltage 24V output from a 72-144V input range, which fits many industrial automation power architectures. Its 960W rating and 40A output current support substantially larger 24V loads than smaller DC-DC converters.
Is the SD-1000H-24 suitable for powering 24V control panels from a high-voltage DC source?
It is designed for exactly that type of conversion when the source is within 72-144V and the load requires regulated 24V DC. With up to 40A output and a 295 x 127 x 41mm case, it is a practical option for higher-power enclosed panel or rack systems.
Can this converter run 24V industrial networking or embedded systems with remote monitoring needs?
It can fit 24V industrial or embedded equipment where the total demand stays within 960W and 40A. The built-in remote ON/OFF control, remote sense, and 12V/0.25A auxiliary output are relevant in monitored equipment platforms.
How does the SD-1000H-24 compare with the other 1000-series DC-DC models?
Among the listed high-power siblings, SD-1000H-12 and SD-1000L-12 are 720W models at 12V and 60A, SD-1000H-24 and SD-1000L-24 are 960W models at 24V and 40A, and SD-1000H-48 and SD-1000L-48 are 1008W models at 48V and 21A. This SD-1000H-24 version specifically combines a 72-144V input range with a 24V, 40A output.
Is the SD-1000H-24 rated for outdoor use or temperature extremes?
The specified operating temperature range is -20°C to +60°C. No IP rating is listed, so the product data here supports temperature evaluation but does not state outdoor enclosure protection.
