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 the RT-65A be used in a larger industrial control panel than the RT-50 models?
Yes. The RT-65A is rated for 66.1W total and lists 5V at 6A, which gives it more stated capacity on the main output than the 50W-class versions shown here. Its triple output configuration of 5V, 12V, and -5V also suits control panels that need multiple DC rails from one supply.
Is the RT-65A a fit for automation or embedded systems with heavier 5V logic loads?
It can be a better fit than the lower-power RT models when the 5V section needs more headroom, because the listed main output is 5V at 6A. The supply is constant voltage and rated for 66.1W total. That makes it relevant for denser logic, controller, or interface assemblies that still need 12V and -5V rails in the same unit.
Can I use the RT-65A for industrial test racks or service fixtures with multiple low-voltage rails?
Yes, if the rack or fixture fits within the 66.1W total rating. The model specification includes 5V, 12V, and -5V outputs, and the main listed 5V rail is 6A. Its 88-264VAC input also helps when test equipment may be used in varied AC environments.
Does the RT-65A work in warm factory cabinets or vibration-prone equipment?
The listed operating range is -25°C to +70°C, and the features mention 5G vibration resistance and 70°C operation. Those are useful indicators for indoor industrial environments with heat and vibration. No IP rating is shown in the provided specs, so outdoor or exposed-environment use is not confirmed here.
How does the RT-65A compare with the nearby RT family models?
Based on the figures provided, RT-50A is 46.5W and 5V 4A, RT-50B is 50W and 5V 4A, RT-50C is 50W and 5V 4A, RT-50D is 51W and 5V 3A, RT-65A is 66.1W and 5V 6A, RT-65B is 64.6W and 5V 5A, RT-65C is 65.5W and 5V 5A, and RT-65D is 68W and 5V 4A. RT-65A sits above the 50W-class models on stated power and main 5V current, while remaining below the 125W-class units.
