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-15 for 15V industrial electronics or control assemblies?

Yes, this unit provides constant-voltage 15V output with up to 7.6A and 114W available. It is suitable for industrial or embedded equipment that is specifically designed for 15V DC and stays within those output limits.

Is the EPP-120S-15 a fit for 15V test and measurement equipment?

It can be, provided the equipment requires 15V constant-voltage input and draws no more than 7.6A. The 114W rating applies continuously, with 142.5W and 9.5A available as a 10-second peak.

Can this 15V model support embedded systems inside industrial equipment?

Yes, for embedded systems that call for 15V DC and need up to 114W total power. Its 80-264VAC input range also supports use in equipment intended for a wide range of AC input conditions.

Is the EPP-120S-15 appropriate for outdoor or exposed use?

The operating temperature range is -30°C to +85°C, with the load derated at higher ambient temperatures per the derating curve. Since no IP rating is listed, it is better suited to protected indoor assemblies or enclosed systems than to direct outdoor exposure.

How does the EPP-120S-15 compare with other 15V models in the series?

In the EPP-120S series covered by this datasheet, the EPP-120S-15 is the only 15V model: 114W at 7.6A convection-cooled, 142.5W and 9.5A peak for 10 seconds, and 92% typical efficiency. It combines this output with a 3" x 2" size and 76.2 × 50.8 × 28 mm dimensions; other EPP families are not specified on this sheet.
