Test conditions and notes10

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.(In order to meet tolerance, it is recommended that CH1 load > 5% rated current.)
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. Testing harmonic current at 85%load.
10. 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 RD-125-2448 for a compact 24V control or automation enclosure?

Yes, this model provides a listed 24V output at 2A in a 144W enclosed AC-DC power supply format. That makes it relevant for smaller control or automation assemblies built around a 24V rail. Its 199.0 × 98.0 × 38.0 mm housing can also help in tighter enclosures.

Is the RD-125-2448 suitable for 24V embedded equipment that needs dual outputs?

It can be a fit where the equipment needs a 24V rail and benefits from a dual output power supply. The listed output is 24V at 2A, with total rated power of 144W. Its enclosed construction and 0.59 kg weight also make it practical for compact equipment builds.

Can this model be used in industrial monitoring or light process equipment with 24V electronics?

For light process or monitoring equipment using 24V electronics, the RD-125-2448 offers a 24V output at 2A in a 144W class supply. The features also specify 5G vibration resistance and operation up to +70°C. Those are relevant specs for indoor equipment exposed to more demanding operating conditions.

Is the RD-125-2448 designed for outdoor service or wide indoor temperature swings?

The operating temperature range is listed as -25°C to +70°C, so it is specified for wide-temperature indoor use. No IP rating appears in the provided specs, so the available data does not confirm outdoor ingress protection. The environmental details given are the temperature range and 5G vibration resistance.

How does the RD-125-2448 compare with other RD models in the same family list?

Within the 125W subgroup shown here, RD-125-1224 is 133.2W 12V 3.7A, RD-125-1248 is 138W 12V 2.3A, and this RD-125-2448 is 144W 24V 2A. The rest of the provided siblings include RD-125A at 130.9W 5V 7.7A, RD-125B at 133.4W 5V 4.6A, RD-3513 at 35.1W 13.5V 1.3A, RD-35A at 32W 5V 4A, RD-35B at 35W 5V 2.2A, RD-50A at 54W 5V 6A, RD-50B at 53.6W 5V 4A, RD-65A at 66W 5V 6A, RD-65B at 68W 5V 4A, and RD-85A and RD-85B at 88W 5V 8A. RD-125-2412, RD-125-4812, RD-125-4824, RD-125A-OB, RD-125NB, and RD-65A-OB are listed without complete specs in the provided data.
