Test conditions and notes8

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. Derating may be needed under low input voltages. Please check the derating curve for more details.
6. Touch current was measured from primary input to DC output.
7. 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).
8. 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 EPS-45S-15 for a 15V industrial controller or instrumentation module?

Yes, this is a constant voltage 15V supply rated for up to 3A and 45W. It fits industrial control, instrumentation, or embedded equipment designed for 15V DC within those ratings.

Is the EPS-45S-15 a fit for embedded electronics that need 15V DC from AC input?

It can be used for embedded systems that require a regulated 15V output and draw no more than 3A. The 80-264VAC input range supports use in equipment intended for broad AC input conditions.

Would this model work for a compact automation or test system with a 15V load?

Yes, provided the system needs constant 15V and its total load stays within 45W and 3A. Its 76.2 x 50.8 x 24.0 mm dimensions make it easier to place in compact internal layouts.

Can the EPS-45S-15 be used for 15V communication or signal-processing equipment?

It is suitable for communication, sensing, or signal-processing equipment that is specified for constant 15V input. The electrical limit is 3A with a maximum rated power of 45W.

Is the EPS-45S-15 intended for wet or exposed outdoor environments?

No IP rating is listed for this model, so the product information does not confirm protection against water or dust exposure. The operating temperature range is -30°C to +70°C, which addresses temperature capability but not environmental sealing.

How does the EPS-45S-15 compare with other 15V EPS power supplies?

The EPS-45S spec sheet lists one 15V model, the EPS-45S-15 at 45W and 3A. The other versions are EPS-45S-3.3 at 26.4W, 3.3V, 8A; EPS-45S-5 at 40W, 5V, 8A; EPS-45S-7.5 at 40.5W, 7.5V, 5.4A; EPS-45S-12 at 45.6W, 12V, 3.8A; EPS-45S-24 at 45.6W, 24V, 1.9A; and EPS-45S-48 at 45.1W, 48V, 0.94A. At 45W, the EPS-45S-15 sits just below the 45.1W 48V version and the 45.6W 12V and 24V versions.
