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-48 for 48V telecom or network power systems?
Yes, this model is a constant-voltage 48V converter with a 72-144V input range, which aligns with many 48V DC system architectures. Its 1008W output rating and 21A maximum output current suit higher-power 48V equipment loads.
Is the SD-1000H-48 suitable for industrial 48V automation or motion-control subsystems?
It can be used where the source voltage is within 72-144V and the downstream equipment requires regulated 48V DC. The 1008W capacity and 21A output make it appropriate for heavier 48V loads than smaller automation converters.
Can this converter support 48V IT or communications equipment in a rack-mounted setup?
Yes, the 41mm-high case (295 x 127 x 41mm) is relevant for rack or cabinet integration where a 48V DC rail is required. The output is 48V at up to 21A, and the feature set includes remote ON/OFF control, remote sense, and a 12V/0.25A auxiliary output.
How does the SD-1000H-48 differ from the other SD-1000H and SD-1000L models?
The listed high-power siblings split into 12V at 60A and 720W, 24V at 40A and 960W, and 48V at 21A and 1008W across both H and L versions. The SD-1000H-48 is the 48V, 21A, 1008W member of the H-input group with a 72-144V input range.
Can the SD-1000H-48 be used outdoors or in demanding temperature conditions?
Its operating temperature range is listed as -20°C to +60°C, so the temperature capability is defined within those limits. No IP rating appears in the provided specs, so this page does not indicate outdoor sealing or water ingress protection.
