Test conditions and notes6
- 1. All parameters NOT specially mentioned are measured at 24,48VDC 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. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSD-300-5 / -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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
- 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-300C-5 to power 5V industrial controllers or embedded boards from a 33.6 to 62.4V DC source?
Yes. The RSD-300C-5 converts 33.6 to 62.4V input to a constant 5V output. With 210W capacity and 42A output current, it fits higher-current 5V industrial and embedded loads within those ratings.
Is this 5V converter suitable for powering multiple 5V automation modules on a higher-voltage DC bus?
It can be suitable where the combined load stays within 42A and 210W. This model is intended for systems that need regulated 5V constant-voltage output from a 33.6 to 62.4V DC input range.
Would the RSD-300C-5 work for 5V industrial computing or data acquisition equipment?
Yes, if the equipment requires a regulated 5V rail and remains within the 42A output and 210W limit. That makes it relevant for higher-current 5V embedded computing and data acquisition use cases on a higher-voltage DC source.
Can this model be used in vibration-heavy machinery or mobile automation platforms?
Yes. The specs list 5G vibration resistance, which supports use in moving or vibration-prone equipment. It still provides 5V constant-voltage output with up to 42A and 210W.
Is the RSD-300C-5 intended for outdoor environments?
The specs show an operating temperature range of -40°C to +55°C at full load, up to +70°C at 60% load by free-air convection, or +70°C at full load with an external base plate; -40°C to +85°C is the storage range. No IP rating is listed, so the provided data does not confirm outdoor or weather-exposed use.
How does the RSD-300C-5 differ from the other RSD-300C models?
The RSD-300C family listed here includes RSD-300C-5 at 210W, 5V, 42A, RSD-300C-12 at 300W, 12V, 25A, RSD-300C-24 at 300W, 24V, 12.5A, and RSD-300C-48 at 302.4W, 48V, 6.3A. The differences are in output voltage, output current, and the listed wattage.
