Test conditions and notes7
- 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 0% to 100% rated load.
- 6. 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 )
- 7. 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 RQ-50D in a compact control system that needs 5V logic and 24V with +/-12V rails?
Yes, if the load matches the unit's 53.4W total power rating. The RQ-50D is a quad output constant voltage supply with a 5V main output rated at 3A, plus 24V, 12V, and -12V outputs. That output combination suits smaller mixed-voltage control assemblies.
Is the RQ-50D appropriate for low-power embedded or automation electronics with several voltage rails?
It is intended for multi-rail designs rather than a single high-current 5V load. The main 5V output is 3A, total power is 53.4W, and the input range is 88-264VAC. Those specs fit compact embedded or automation equipment that needs moderate 5V current plus additional DC rails.
Can the RQ-50D work for industrial sensing or interface equipment in a small enclosure?
Yes, where the equipment uses 5V control electronics together with 24V and +/-12V rails. The supply measures 99.0 x 97.0 x 36.0 mm and weighs 0.41 kg, so it is suited to tight packaging. Its miniature size is useful in smaller control boxes and interface modules.
Is the RQ-50D suitable for indoor industrial environments with temperature swings?
The specified operating temperature range is -25°C to +70°C, and the product is rated to withstand 5G vibration. Those specs support use in demanding indoor industrial environments. No IP rating is provided in the supplied specs, so exposed outdoor use is not established here.
How does the RQ-50D compare to the other Mean Well RQ models in this list?
The RQ-50D is rated at 53.4W with a 5V main output of 3A. Other listed siblings are RQ-50B at 45.5W and 5V 5A, RQ-50C at 50W and 5V 5A, RQ-65B at 62.5W and 5V 6A, RQ-65C at 65W and 5V 5A, RQ-65D at 68W and 5V 4A, RQ-85B at 80.7W and 5V 7A, RQ-85C at 82.5W and 5V 7A, RQ-85D at 84W and 5V 6A, RQ-125B at 120W and 5V 11A, RQ-125C at 122.5W and 5V 10A, and RQ-125D at 124W and 5V 8A.
