Test conditions and notes7
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  5. 5. Derating may be needed under low input voltage. Please check the static characteristics for more details.
  6. 6. 33% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
  7. 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).

FAQ

Can I use the EPS-15-12 for a 12V sensor or small controller project?

Yes, it is a constant-voltage 12V supply rated for 15W and 1.25A, which suits low-power 12V electronics. It is best matched to equipment that needs a fixed 12V DC rail and stays within that output limit.

Is the EPS-15-12 suitable for embedded systems with modest 12V power demand?

It can be a fit for embedded hardware that needs 12V and draws up to 1.25A. The compact 63.5 x 45.7 x 24.0 mm footprint also makes it practical where space is tight.

Can this model power a small 12V automation accessory?

Yes, for light-duty automation loads that require 12V constant voltage and remain under 15W. It is more appropriate for smaller auxiliaries than for high-current 12V equipment.

Does the EPS-15-12 work for protected indoor environments only?

The specified operating temperature is -30°C to +70°C, with output derating at higher temperatures per the derating curve, so the temperature range is broad. No IP rating is listed, so outdoor exposure would normally require a separate protective enclosure rather than open use.
