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-12 for 12V industrial control equipment?
Yes, this is a constant-voltage 12V supply rated for 9.5A and 114W. It fits 12V industrial or embedded equipment that needs higher current while staying within the 9.5A and 114W output limits.
Is the EPP-120S-12 suitable for 12V automation accessories or panel devices?
It can be used where the connected automation accessory is designed for 12V DC and the total load does not exceed 9.5A. The 80-264VAC input range also makes it practical for equipment used across different AC mains conditions.
Can this model power 12V embedded systems that need more than basic current capacity?
Yes, this model delivers up to 114W and 9.5A at 12V continuously, with 141.6W and 11.8A available as a 10-second peak. That makes it useful for denser 12V embedded assemblies, industrial electronics, or test fixtures that need more headroom at 12V.
Is the EPP-120S-12 intended for outdoor use?
Its operating temperature range is -30°C to +85°C, with the load derated at higher ambient temperatures according to the derating curve. But no IP rating is listed, so it should be used in protected indoor equipment or a suitable enclosure rather than exposed outdoor conditions.
How does the EPP-120S-12 compare with other 12V options in the EPP family?
This datasheet covers only the EPP-120S series, in which the EPP-120S-12 is the only 12V model: 114W at 9.5A convection-cooled, 141.6W and 11.8A peak for 10 seconds, and 91% typical efficiency. It has a 3" x 2" form factor with 76.2 × 50.8 × 28 mm dimensions; other EPP families are not specified on this sheet, so check their own datasheets.
