Test conditions and notes8
- 1. All parameters NOT specially mentioned are measured at 230VAC 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, when multi-channel output, it is recommended that CH1 load > 10%.
- 4. Line regulation is measured from low line to high line at rated load.
- 5. Load regulation is measured from 20% to 100% rated load, and other output at 60% rated load.
- 6. Each output can work within current range. But total output power can't exceed rated output power.
- 7. 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 )
- 8. 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 RD-65A for a PLC cabinet that needs 5V electronics and a 12V auxiliary rail?
Yes, this dual output constant voltage model is designed for 5V and 12V output use and is rated for 66W total. The 5V output is rated at 6A, which gives it more 5V capacity than the 50W-class versions. That makes it a practical choice for PLC-related control hardware with moderate 5V demand.
Is the RD-65A suitable for industrial controllers or embedded systems that run continuously in warmer enclosures?
It is specified for operation from -25C to +70C, so it is suited to equipment that sees elevated enclosure temperatures within that range. The main 5V output is 6A and total rated power is 66W, which fits mid-range control and embedded loads. The 88-264VAC input also supports use on common global AC input ranges.
Can the RD-65A handle applications where vibration resistance matters?
This power supply is specified to withstand 5G vibration, which is relevant for industrial automation equipment and machine-mounted enclosures. Its main output remains a 5V constant voltage rail at 6A, with 66W total available across the dual output design. That means it is best matched to moderate-power electronics rather than high-current DC loads.
Should the RD-65A be used indoors or outdoors?
The temperature specification of -25C to +70C supports a wide range of indoor industrial conditions. No IP rating is provided in the supplied specs, so it should be treated as a unit for protected indoor use or installation inside an enclosure, not for direct outdoor exposure. Environmental suitability should therefore be based on enclosure protection as well as temperature.
Where does the RD-65A sit within the RD family range?
The RD-65A is the 66W model in the RD-65 series, featuring a 5V 6A main output and a 12V 3A secondary output. It sits alongside the RD-65B, which offers 5V 4A and 24V 2A outputs. Both models share the same 65W-class form factor and universal input range.
