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 0.1μF & 47μF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. The power supply is considered a component which will be installed into a final equipment. 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 )
  5. 5. Derating may be needed under low input voltages. Please check the derating curve for more details.
  6. 6. Heat Sink HS1,HS2 can not be shorted.
  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 EPP-300-24 for a 24V PLC, sensor, or industrial I/O system?

Yes, if the system requires a constant 24Vdc source and the total load does not exceed 199.9W or 8.33A with convection cooling, or 300W or 12.5A with 20.5CFM forced airflow. That makes it relevant for many 24V automation loads in the 200-300W class.

Is this a good power supply for 24V embedded computers or industrial communication gear?

It can be, provided the equipment is specified for regulated 24V constant-voltage input and stays within the 8.33A convection-cooled output limit, or 12.5A with 20.5CFM airflow. The unit's 90-264VAC input also supports operation across a broad range of AC mains conditions.

Can the EPP-300-24 power a 24V control cabinet accessory group?

It is suitable for grouped 24Vdc loads when the combined demand remains at or below 199.9W and 8.33A with convection cooling (300W and 12.5A with 20.5CFM airflow). Buyers should confirm the full cabinet load against both current and wattage to avoid oversizing assumptions.

Can this model be used in outdoor or unprotected environments?

Its operating temperature range is listed as -30 degrees C to +70 degrees C, with output derating at higher temperatures per the derating curve. No IP rating is provided in the product data, so the specs do not confirm suitability for direct outdoor exposure, rain, or washdown areas.
