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 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 )
6. 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 EPS-120-15 for 15V industrial electronics?

Yes, if the equipment specifically requires a 15V constant voltage input. This model delivers 15V output with 5.6A and 84W under convection cooling, or 8A and 120W with a 10CFM fan.

Is the EPS-120-15 a good fit for 15V test and measurement equipment?

It can be used for test, measurement, or control hardware that is designed for 15V DC operation. The output capability is 15V at 5.6A and 84W with convection cooling, or 8A and 120W with a 10CFM fan.

Can this 15V power supply support embedded boards and interface modules?

It is suitable for embedded or industrial modules that need a regulated 15V source rather than 12V or 24V. The power envelope is 84W at 5.6A with convection cooling, or 120W at 8A with a 10CFM fan.

Is the EPS-120-15 meant for indoor or outdoor conditions?

The specs show an operating temperature range of -30°C to +70°C with derating per the derating curve, which gives a defined thermal range. However, no IP rating is listed, so the provided data does not establish weather, dust, or water resistance for outdoor exposure.

How does the EPS-120-15 compare with the other EPS-120 models?

With convection cooling, the EPS-120 options are 12V at 84W and 7A, 15V at 84W and 5.6A, 24V at 84W and 3.5A, 27V at 85W and 3.15A, and 48V at 84W and 1.75A; a 10CFM fan raises them to 120W (121.5W for 27V). This 15V version keeps the same compact 101.6 x 50.8 x 29 mm form factor while changing the output voltage and available current.
