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 0.1uF & 47uF 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.)
  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 RID-85B for 5V control electronics in an automation cabinet?

Yes, it can fit 5V control electronics that stay within its 88W rating and 8A output current. The supply accepts 88-264VAC input and is built as an enclosed dual-output unit for equipment integration.

Is the RID-85B a good fit for embedded monitoring or interface boards with lighter 5V loads?

It is better suited to lighter 5V embedded loads because its listed output current is 8A rather than 4A. The miniature enclosed design and 0.6 kg weight can also help where equipment space and mounting mass are limited.

Can the RID-85B be used in industrial equipment that runs at elevated ambient temperatures?

It is rated for operation from -25°C to +70°C, so the listed temperature range supports use inside industrial equipment with higher ambient conditions. The feature list also states 5G vibration resistance for more demanding machine environments.

Is the RID-85B intended for exposed outdoor installations?

No outdoor IP rating is provided in the supplied specs. The listed data supports temperature operation from -25°C to +70°C, but environmental sealing for direct outdoor exposure is not specified.

What are the main RID series alternatives to the RID-85B?

The supplied siblings include RID-50A at 50W 5V 2A, RID-50B at 50W 5V 1.4A, RID-65A at 65W 5V 3A, RID-65B at 65W 5V 2A, and RID-85A at 85W 5V 8A. Other listed options are RID-125-1205 at 125W 5V 3A, RID-125-1224 at 125W 12V 3.7A, RID-125-1248 at 125W 12V 2.3A, RID-125-2405 at 125W 5V 3A, and RID-125-2448 at 125W 24V 22A, while the RID-85B itself is 85W 5V 8A.
