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 0.1uf & 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 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. Strongly recommended that external output capacitance should not exceed 5000uF.
- 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-30G-5 for 5V industrial computers, SBCs, or USB-powered control electronics?
Yes, it is suitable for regulated 5V loads when the total demand stays within 30W and 6A. That makes it relevant for compact industrial computing and embedded electronics that run on 5V constant-voltage power.
Is the RSD-30G-5 appropriate for powering 5V automation peripherals from a 9-36VAC source?
It is a fit for 5V automation peripherals if the input is within 9-36VAC and the load does not exceed 30W or 6A. The constant-voltage output is intended for electronics that require a stable 5V rail.
Can this converter be used for 5V embedded systems in moving equipment?
Yes, for 5V embedded systems up to 30W and 6A, this model aligns with that use case. Its 5G vibration specification and -40°C to +70°C operating range are relevant for equipment exposed to motion and broader temperature variation.
Is the RSD-30G-5 suitable for outdoor cabinets or exposed environments?
The provided specifications define an operating temperature range of -40°C to +70°C, but they do not provide an IP rating. That means thermal limits are stated, while exposure resistance for outdoor use is not established by the data shown.
