Test conditions and notes7
  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 0.1ΞΌF & 47ΞΌF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Line regulation is measured from low line to high line at rated load.
  5. 5. Load regulation is measured from 0% to 100% rated load.
  6. 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 β€œEMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  7. 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 RS-50-24 for 24V PLC I/O, sensors, or compact automation loads?

Yes, if the connected 24V DC load does not exceed 2.2A and the total power stays within 52.8W. That makes it suitable for many low-power industrial control devices that are designed for a constant 24V input.

Is the RS-50-24 a good fit for 24V industrial communication or control electronics?

It can be used where the equipment requires constant 24V output and stays within the supply's 2.2A and 52.8W ratings. This is typically the right class of supply for compact 24V control electronics rather than higher-draw 24V loads.

Can this 24V power supply support small machine or panel-mounted accessories?

It can support 24V accessories that are specified for constant-voltage operation and remain at or below 2.2A. The 52.8W output makes it better suited to modest 24V panel devices than to larger 24V equipment with heavier current demand.

How does the RS-50-24 compare with other 24V models in the RS series?

The listed 24V RS models are RS-15-24 at 15W and 0.62A, RS-25-24 at 26.4W and 1.1A, RS-35-24 at 35W and 1.5A, RS-50-24 at 52.8W and 2.2A, RS-75-24 at 76.8W and 3.2A, RS-100-24 at 108W and 4.5A, and RS-150-24 at 156W and 6.5A. The RS-50-24 is a mid-range 24V option between the 35W and 76.8W models.

Can the RS-50-24 handle industrial temperature swings, and is it outdoor-rated?

The operating temperature range is -25Β°C to +70Β°C, and the product is specified to withstand 5G vibration. Because no IP rating is provided, the published specifications do not establish outdoor exposure resistance, so it is better treated as a protected-environment power supply.
