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 RID-50B for low-current 5V control boards in industrial equipment?
Yes, if the control boards require 5V DC and stay within the 53.6W total and 4A CH1 rating. This makes it better aligned with lighter-duty 5V electronics than loads that need more current headroom.
Is the RID-50B suitable for 5V embedded controllers or interface modules?
It is suitable for embedded controllers or interface modules designed for 5V DC with demand up to 4A. The 99.0 × 97.0 × 36.0 mm enclosure also supports use in compact industrial or IT housings.
Can this power supply be used for 5V monitoring or automation electronics with modest current draw?
Yes, for 5V monitoring and automation electronics that fit inside the 53.6W total and 4A CH1 output limits. It is a practical choice when the load is lighter and a larger 5V model is not required.
Can the RID-50B be used outdoors or in exposed areas?
The specs show an enclosed power supply with an operating range of -25°C to +70°C, but no IP rating is listed. It is therefore better suited to protected indoor enclosures than direct outdoor or wet exposure.
How does the RID-50B compare with RID-50A, RID-65A, and the larger RID models?
RID-50B is 53.6W total, with CH1 at 5V/4A and CH2 at 24V/1.4A. In the listed family, RID-50A is 54W, CH1 5V/6A, CH2 12V/2A; RID-65A is 65W, 5V, 3A; RID-65B is 65W, 5V, 2A; RID-85A is 85W, 5V, 4A; RID-85B is 85W, 5V, 2A; RID-125-1205 is 125W, 5V, 3A; RID-125-1224 is 125W, 12V, 3.7A; RID-125-1248 is 125W, 12V, 2.3A; RID-125-2405 is 125W, 5V, 3A; and RID-125-2448 is 125W, 24V, 22A.
