Test conditions and notes9
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 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. 4. Line regulation is measured from low line to high line at rated load.
  5. 5. Load regulation is measured from 20% to 100% rated load, and other output at 60% rated load.
  6. 6. Each output can work within current range. But total output power can't exceed rated output power.
  7. 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. 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. 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-85B for a multi-output industrial controller that needs more 5V current than the 65W models?

Yes, this version raises the main 5V output to 7A and the total rated power to 80.7W. The product name also lists 12V, -5V, and -12V outputs, so it fits multi-rail control or interface hardware that needs more 5V capacity than lower-power siblings.

Is the RQ-85B suitable for embedded systems that use 5V logic and both positive and negative support rails?

It can be suitable because this quad output model includes 5V, 12V, -5V, and -12V outputs in one unit. With 5V rated at 7A and total power at 80.7W, it supports higher 5V demand than the 62.5W and 65W variants listed in the same family.

Can the RQ-85B be used in automation equipment exposed to vibration or limited cabinet space?

The listed dimensions are 159 x 97 x 38 mm and the weight is 0.6 kg, so it remains relatively low-profile for cabinet integration. The features also state miniature size and 5G vibration resistance, which is relevant for industrial and automation environments.

Is the RQ-85B appropriate for outdoor or high-temperature operating conditions?

Its operating temperature range is specified as -25 degrees C to +70 degrees C, so it is rated across a wide temperature span. No IP rating is given in the supplied specs, so the product data here does not verify protection against rain, dust ingress, or exposed outdoor conditions.

How does the RQ-85B differ from the other RQ series models listed here?

The supplied siblings are RQ-50B at 45.5W and 5V 5A, RQ-50C at 50W and 5V 5A, RQ-50D at 53.4W and 5V 3A, RQ-65B at 62.5W and 5V 6A, RQ-65C at 65W and 5V 5A, RQ-65D at 68W and 5V 4A, 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. RQ-125ND appears in the sibling list as well, but no wattage or current values are supplied for that model.
