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 0.1uf & 47uf 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 http://www.meanwell.com)
  5. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.
  6. 7. 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-500L-48 for 48V industrial networking or control equipment?

Yes, if the equipment requires constant 48V DC and the total load stays within 10.5A and 504W. The converter accepts a 19-72V input range and delivers regulated 48V output for higher-voltage DC systems.

Is the SD-500L-48 suitable for 48V embedded or edge-computing platforms?

It can be used where the platform is designed for a constant 48V input and the source is within the 19-72V range. With 504W output capacity, it fits higher-power 48V embedded and industrial electronics applications.

Can this converter power 48V automation devices from a variable DC source?

Yes, for automation loads that need regulated 48V DC up to 10.5A. The 4:1 wide input range supports source variation across 19-72V while maintaining constant-voltage output.

Can the SD-500L-48 be used in communications equipment with a 48V DC architecture?

It is a fit for communications or control equipment designed around 48V DC, as long as the total demand does not exceed 504W. The listed remote ON/OFF control and remote sense features are also relevant in supervised equipment systems.

How does the SD-500L-48 compare with the other SD-500L models?

The SD-500L-48 is rated for 504W at 48V and 10.5A. The SD-500L-12 is 480W at 12V and 40A, and the SD-500L-24 is 504W at 24V and 21A. All three share the 19-72V input range, 215.0 × 115.0 × 50.0 mm dimensions, 1.15 kg weight, and -20°C to +60°C operating range.

Is the SD-500L-48 rated for outdoor environments?

The provided specs list an operating temperature range of -20°C to +60°C. They do not list an IP rating, so the supplied data does not confirm outdoor or water-exposed use without an additional protective enclosure.
