Test conditions and notes8
  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. 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 )
  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. EPS-35-24/27/36/48 without Hs1.
  8. 8. 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-35-27 for a 27V industrial control device or automation subassembly?

Yes, it is a constant-voltage 27V supply rated for 35.1W and 1.3A, which fits equipment that specifically requires a 27V DC source within that load range. It is best suited to compact internal industrial, embedded, or automation assemblies where the device load stays at or below 1.3A.

Is the EPS-35-27 suitable for embedded electronics that need a small internal 27V power supply?

It can be a good fit for embedded designs that need 27V DC and up to 35.1W from an AC input of 85-264VAC. The 76.2 × 50.8 × 24.0 mm size and 0.085 kg weight make it more appropriate for space-conscious internal equipment than larger chassis supplies.

Can this power supply run a 27V panel device, interface module, or low-power actuator load?

It is intended for 27V constant-voltage loads drawing up to 1.3A, so it fits panel devices, interface electronics, or similar low-power automation loads that stay within 35.1W. The key selection point is matching both the required 27V output and the current draw to the 1.3A limit.

Is the EPS-35-27 suitable for outdoor or harsh-environment use?

The listed operating temperature is -30°C to +70°C, but no IP rating is provided in these specs. That means the product data here supports temperature capability, but does not indicate sealed protection for outdoor, wet, or washdown exposure.
