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. 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 )
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-60L-12 to run a 12V PLC, relay module, or control panel device from a higher-voltage DC bus?

This model provides a constant 12V output at up to 5A, with a 60W power rating. Its specified input range is 18-72VDC, so it fits applications where the source is within that range and the 12V load remains within 60W.

Is the RSD-60L-12 suitable for 12V industrial communication or monitoring equipment?

It can support 12V industrial electronics that need regulated constant-voltage output. The available output is 12V at up to 5A, so the connected equipment needs to stay within the 60W capacity.

Can this converter be used for embedded or vehicle-style 12V electronics in equipment exposed to vibration?

The datasheet specifies 5G vibration resistance (IEC61373) and operation from -40°C to +55°C at full load, or up to +70°C at 60% load by free air convection (full load with an external base plate). Those published limits make it relevant for embedded and industrial systems that need 12V output in mechanically demanding environments.

Will the RSD-60L-12 work in hot or cold enclosures, and is it rated for outdoor exposure?

It operates from -40°C to +55°C at full load; at +70°C it is limited to 60% load by free air convection, or full load when mounted on an external base plate. No IP rating is listed in the provided data, so outdoor or weather-exposed use is not established by these specs alone.

How does the RSD-60L-12 compare with the other RSD-60L output versions?

The RSD-60L-12 is 60W with a 12V, 5A output. In the same RSD-60L group, the RSD-60L-3.3 is 39.6W at 3.3V and 12A, the RSD-60L-5 is 60W at 5V and 12A, and the RSD-60L-24 is 60W at 24V and 2.5A.
