Test conditions and notes11

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.
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. 10% duty cycle maximum within every second. Average output power should not exceed the rated power.
10. Testing harmonic current at 85%load.
11. 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-125-2405 for 5V embedded computing or controller boards in industrial equipment?

It can fit 5V embedded computing or controller boards when the load stays within its 3A output current and 125W power rating. The enclosed design supports use inside industrial equipment rather than in exposed environments.

Is the RID-125-2405 suitable for 5V HMI, display, or interface electronics?

Yes, it is aligned with 5V electronics such as display or interface hardware because the rated output is 5V at 3A. It is best matched to equipment that specifically requires a 5V rail.

Can the RID-125-2405 power 5V monitoring or communications hardware in automation systems?

This model can support 5V monitoring or communications hardware if the total load remains within 3A and 125W. The isolated dual-output design can also matter in systems where output separation is required.

Is the RID-125-2405 rated for indoor control cabinets or exposed outdoor use?

Its operating temperature range is -25°C to +70°C, so it is suitable for a broad range of indoor equipment conditions. The provided specifications do not include an IP rating, so exposed outdoor use is not confirmed.

How does the RID-125-2405 differ from the other RID models in this group?

The sibling list includes RID-125-1205 at 125W, 12V/5V; RID-125-1224 at 133.2W, 12V/24V; RID-125-1248 at 138W, 12V/48V; RID-125-2448 at 144W, 24V/48V. The RID-125-2405 is the 125.4W model with 24V and 5V outputs.
