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-15-27 for a 27V control or instrumentation circuit?

Yes, if the equipment requires constant 27V DC and stays within 0.56A and 15.12W. It is intended for lighter 27V loads rather than systems with higher current demand.

Is the EPS-15-27 suitable for a compact 27V embedded device?

It can fit small embedded hardware built around a 27V input rail, provided the total load remains under 15.12W. The small 63.5 x 45.7 x 24.0 mm size can help in compact housings.

Can this power supply run a low-power 27V automation module?

Yes, for low-power automation or interface modules that need a fixed 27V output and draw no more than 0.56A. The 85-264VAC input range also supports use across a wide AC input span.

Is the EPS-15-27 okay for harsh temperature environments?

The operating range is -30°C to +70°C, with output derating at higher temperatures per the derating curve, which is broad for temperature exposure. No IP rating is listed, so environmental suitability depends on using it in a protected space or inside an enclosure that adds the required ingress protection.
