Test conditions and notes10
  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 0.1μF & 47μF 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 > 5% 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. Testing harmonic current at 85%load.
  10. 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 RID-125-2448 for a 24V industrial control panel load?

This model is aimed at 24V DC applications and is rated at 144W with 2A output current on CH1. That makes it a fit for industrial control panels, automation assemblies, and other equipment that specifically requires 24V DC within that power range.

Is the RID-125-2448 suitable for 24V automation and machine subsystems?

It can be used for 24V automation subsystems that need up to 144W and 2A on CH1. The enclosed design and isolated dual output format make it more appropriate for protected machine or cabinet environments than exposed field mounting.

Can this power supply support 24V embedded or industrial electronics in a compact enclosure?

Yes, if the equipment is designed for 24V DC and stays within the 144W and 2A ratings. Its 199.0 × 98.0 × 38.0 mm size is useful where enclosure space matters, and the unit is specified for operation up to +70°C.

Is the RID-125-2448 OK for outdoor or washdown locations?

The provided specs list it as an enclosed power supply, but no IP rating is given. That means it is better suited to protected indoor enclosures and controlled industrial spaces rather than outdoor, wet, or washdown exposure.

How does the RID-125-2448 compare with other Mean Well RID series models?

Within the listed siblings, RID-125-2448 is 144W at 24V/48V. Other listed models are RID-125-1205 at 125.4W, 12V/5V; RID-125-1224 at 133.2W, 12V/24V; RID-125-1248 at 138W, 12V/48V; RID-125-2405 at 125.4W, 24V/5V; 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; RID-85A at 85W, 5V, 4A; and RID-85B at 85W, 5V, 2A.
