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 0.1uf & 47uf 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 http://www.meanwell.com)
- 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-1000L-24 to power a 24V industrial control cabinet from a variable DC source?
Yes, this converter is designed for constant voltage output at 24V and can deliver up to 40A. Its listed input range is 19-72V, which suits DC systems that stay within that range.
Is the SD-1000L-24 suitable for 24V automation loads with higher current demand?
It can support 24V automation equipment that needs up to 960W and up to 40A. That makes it a fit where a stable 24V constant voltage supply is required from a 19-72V input source.
Can this converter be used for 24V embedded or mobile electronics running from a wide input bus?
Yes, the 4:1 wide input range supports sources from 19-72V while maintaining a 24V output. With 960W capacity and 40A output current, it is aimed at higher-power 24V DC loads rather than small electronics.
Is the SD-1000L-24 appropriate for indoor equipment in demanding temperature conditions?
The listed operating temperature range is -20°C to +60°C, so it is intended for equipment that operates within that window. No IP rating is provided in the specs, so the product data does not identify it as an outdoor or washdown-rated unit.
How does the SD-1000L-24 compare with the other SD-1000L models?
Within the SD-1000L group, the SD-1000L-12 is rated at 720W, 12V, 60A, the SD-1000L-24 is rated at 960W, 24V, 40A, and the SD-1000L-48 is rated at 1008W, 48V, 21A. All three are part of the same SD-1000L series, so the main differences are output voltage, output current, and total wattage.
