Test conditions and notes6

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. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. 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).
6. The power supply is considered a component which will be installed into a final equipment. All the ClassⅠ(with FG) EMC test are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. 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 )

FAQ

Can I use the EPP-500-24 for a 24V PLC or industrial automation system?

Yes, this supply is built for constant 24V output and can support 24V automation equipment within its rating. The available output is 13.4A with a total power limit of 321W with convection cooling, or 20.8A and 499.2W with 25CFM forced-air cooling.

Is this a good fit for 24V sensors, relays, and control devices in one enclosure?

It can be used when the full 24V load stays within 13.4A and 321W with convection cooling (20.8A and 499.2W with 25CFM forced air). The wide 80-264VAC input range also helps when the equipment may be used across different AC mains conditions.

Can the EPP-500-24 power a 24V embedded or IPC-based system?

It can fit embedded or industrial computer assemblies that are designed for 24V DC input. The compact 127.0 x 76.2 x 41.0 mm size and 0.46 kg weight are useful where space matters.

Is the EPP-500-24 meant for indoor cabinets or outdoor equipment?

The temperature rating of -30C to +70C, with output derating at higher ambient temperatures per the derating curve, supports demanding thermal conditions. Since no IP rating is listed in the provided specs, it is better matched to protected indoor equipment or an enclosure instead of open outdoor exposure.

What are the differences between the EPP-500-24 and the other EPP-500 models?

With convection cooling, the EPP-500 family includes 12V at 26.7A and 320.4W, 15V at 21.3A and 319.5W, 18V at 17.8A and 320.4W, 24V at 13.4A and 321W, 27V at 11.9A and 321.3W, 36V at 8.9A and 320.4W, 48V at 6.7A and 321.6W, and 54V at 5.93A and 320.2W; with 25CFM forced air each reaches about 500W (20.8A at 24V). The 24V version sits in the middle of the range, with lower current than the 12V, 15V, and 18V models and higher current than the 27V, 36V, 48V, and 54V versions.
