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 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 )

FAQ
Can I use the EPP-120S-24 for 24V PLC or automation equipment?
Yes, it supplies constant-voltage 24V output with up to 5A and 120W available. That makes it suitable for 24V automation or industrial electronics that are specified for 24V DC and remain within the 5A and 120W limits.
Is the EPP-120S-24 suitable for 24V sensors, controllers, or industrial subsystems?
It can be used where the subsystem requires 24V constant-voltage power and the total load does not exceed 5A. The 80-264VAC input range is also useful for machines or panels deployed in different AC power environments.
Can this power supply run a 24V embedded control assembly?
Yes, if the assembly is designed for 24V DC and needs no more than 120W total output power. Its 24V, 5A rating fits many mid-power industrial control and embedded applications that use 24V as a standard DC bus.
Can the EPP-120S-24 be used outdoors?
The specified operating temperature range is -30°C to +85°C, with the load derated at higher ambient temperatures according to the derating curve. But there is no IP rating listed, so it is best used in protected indoor equipment or within an enclosure rather than in exposed outdoor conditions.
How does the EPP-120S-24 compare with other 24V EPP models?
This datasheet covers only the EPP-120S series, in which the EPP-120S-24 is the only 24V model: 120W at 5A convection-cooled, 150W and 6.25A peak for 10 seconds, and 93% typical efficiency. It uses the 3" x 2" platform with 76.2 × 50.8 × 28 mm dimensions; other EPP families are not specified on this sheet, so compare them against their own datasheets.
