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-50A for 5V PLC accessories or control electronics?
This unit is intended for 5V DC loads and is rated at 54W with 6A output current on CH1. It is suited to PLC accessories, control electronics, and other industrial devices that specifically call for 5V DC within that output range.
Is the RID-50A a good fit for embedded systems or industrial computing hardware that runs on 5V?
It can be used where the load requires 5V DC and remains within 54W and 6A. The compact 99.0 × 97.0 × 36.0 mm enclosure also helps in space-limited embedded and control builds.
Can this model power 5V instrumentation or test equipment inside a cabinet?
Yes, for cabinet-mounted instrumentation or test equipment designed for 5V DC and no more than 54W or 6A. The enclosed format and isolated dual output make it more appropriate for protected indoor equipment spaces than open exposure.
Is the RID-50A suitable for cold or hot industrial environments?
The operating temperature range is -25°C to +70°C, which supports use in a wide range of indoor industrial environments. Because no IP rating is listed, it should still be placed in a protected enclosure rather than exposed outdoor conditions.
What is the difference between RID-50A and other RID series options?
RID-50A is 54W at 5V (6A) and 12V (2A). Other listed siblings are RID-50B at 53.6W, 5V (4A), 24V (1.4A); RID-65A at 65W, 5V, 3A; RID-65B at 65W, 5V, 2A; RID-85A at 85W, 5V, 4A; RID-85B at 85W, 5V, 2A; 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.
