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-50C for a compact analog control board that needs 5V and +/-15V rails?
Yes, if the total load stays within the product's 50W rating. The RQ-50C uses constant voltage operation, provides a 5V main output at 5A, and includes 15V and -15V outputs in a quad output design. That fits smaller control and analog processing assemblies needing several rails from one supply.
Is the RQ-50C a fit for embedded measurement or instrumentation electronics?
It can be, especially for designs that combine 5V digital logic with +/-15V analog stages. The unit delivers 5A on the 5V rail and comes in a 99.0 x 97.0 x 36.0 mm enclosure. That makes it suitable where multi-rail support is needed but available space is limited.
Can the RQ-50C be used in a low-power automation module with universal AC input?
Yes. The input range is 88-264VAC, so it supports broad AC input conditions, and the total rated power is 50W. For compact automation modules that need 5V logic and +/-15V rails, it can reduce the need for separate supplies.
Is the RQ-50C suitable for outdoor use or only for enclosed indoor equipment?
The operating temperature range is -25°C to +70°C, and the supply is rated to withstand 5G vibration. Those are useful industrial environment specs for enclosed indoor equipment. No IP rating is listed in the supplied data, so outdoor suitability is not confirmed by the available specifications.
What is the difference between the RQ-50C and the other RQ siblings listed here?
The RQ-50C is rated at 50W with a 5V main output at 5A. The sibling list includes RQ-50B at 45.5W and 5V 5A, and RQ-50D at 53.4W and 5V 3A. Other models in the RQ series include RQ-65B at 62.5W, RQ-65C at 65W, RQ-65D at 68W, RQ-85B at 80.7W, RQ-85C at 82.5W, RQ-85D at 84W, RQ-125B at 120W, RQ-125C at 122.5W, and RQ-125D at 124W.
