Test conditions and notes6
- 1. All parameters NOT specially mentioned are measured at 24,48,110VDC 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. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSD-100-5 / -12)
- 5. 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)
- 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 RSD-100D-5 for 5V industrial single-board computers or embedded controllers?
Yes, if the equipment needs a constant 5V supply and the total load stays within 20A. This model provides up to 100W, so it suits higher-current 5V embedded electronics better than lower-current 12V or 24V outputs.
Is the RSD-100D-5 a fit for 5V USB-style logic, gateways, or communications electronics in an equipment enclosure?
It can fit 5V logic and communications hardware when the combined draw does not exceed 20A or 100W. The constant-voltage output makes it appropriate for electronics that expect a regulated 5V rail rather than a constant-current source.
Can this model support a 5V PLC accessory or industrial I/O subsystem?
It is suitable for 5V automation electronics that require stable constant-voltage power up to 20A. That gives more current headroom for dense 5V control loads than the 24V version, which is limited to 4.2A.
Is the RSD-100D-5 suitable for outdoor cabinets or temperature-extreme environments?
The specified operating range is -40°C to +85°C, which supports use across a wide temperature span. No IP rating is shown in the provided specs, so the product data does not confirm outdoor exposure resistance.
What are the main differences between the RSD-100D-5 and the other 100W RSD outputs?
Among the listed 100W-class outputs, the 5V models are 100W at 20A, the 12V models are 100.8W at 8.4A, and the 24V models are 100.8W at 4.2A. In the D versions, RSD-100D-5 is 100W 5V 20A, RSD-100D-12 is 100.8W 12V 8.4A, and RSD-100D-24 is 100.8W 24V 4.2A.
