Test conditions and notes9
- 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. (In order to meet tolerance, it is recommended that CH1 load > 20% rated current for B,C type and CH1 load > 15% rated current for D type.)
- 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. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
- 9. 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-85D for a 5V industrial controller that also needs multiple DC rails in one chassis?
The RQ-85D is a constant-voltage power supply with quad output, and the listed specs include 5V at 6A with 84W total power. That makes it relevant for enclosed industrial or automation equipment that uses a 5V main rail and benefits from a quad-output design.
Is the RQ-85D suitable for embedded test equipment or bench electronics that run on 5V?
It can fit embedded or lab-style equipment that needs a regulated 5V constant-voltage source up to 6A. The compact 159.0 × 97.0 × 38.0 mm size and 0.6 kg weight also make it practical where internal space is limited.
Can this power supply support a 5V automation subsystem inside a machine cabinet?
It is suited to enclosed automation use where the load requires 5V constant voltage and stays within 6A and 84W. The listed features also note 5G vibration resistance and operation up to +70°C, which aligns with industrial cabinet environments.
Is the RQ-85D appropriate for indoor or outdoor environments?
The provided specs list an operating temperature range of -25°C to +70°C, but they do not list an IP rating. Based on the listed data, it is better treated as a power supply for protected indoor enclosures rather than exposed outdoor locations.
How does the RQ-85D compare with other RQ series models?
The RQ-85D is 84W with outputs of 5V 6A, 12V 2A, 24V 1A, and -12V 0.5A. Other RQ-85 models include RQ-85B (80.7W, 5V 7A, 12V 3.1A, -5V 0.5A, -12V 0.5A) and RQ-85C (82.5W, 5V 7A, 15V 2.5A, -5V 0.5A, -15V 0.5A). Higher-power RQ-125 series models are also available.
