Test conditions and notes6
  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 voltages. Please check the derating curve for more details.
  6. 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 EPP-100-27 for 27V industrial control or test equipment?

Yes, this model is a constant-voltage 27V supply rated for 2.8A and 75.6W with convection cooling, or 3.71A and 100.17W with a 20CFM fan. It fits industrial or embedded equipment that specifically requires 27V DC and stays within those output limits.

Is the EPP-100-27 suitable for a 27V automation panel subsystem?

It can be used for a 27V automation subsystem when the connected load needs constant-voltage 27V power and draws no more than 2.8A (3.71A with a 20CFM fan). The wide 90-264VAC input also helps when the equipment is deployed across facilities with different AC supply standards.

Can this 27V power supply run embedded electronics that need stable DC output?

Yes, the EPP-100-27 is designed for constant-voltage output at 27V with up to 75.6W available with convection cooling (100.17W with a 20CFM fan). That makes it appropriate for embedded electronics, instruments, or control assemblies that are designed for 27V DC and need 2.8A or less (3.71A with the fan).

Is the EPP-100-27 meant for outdoor or exposed environments?

This unit has an operating temperature range of -30°C to +70°C, with output derating at higher temperatures (see the derating curve), but no IP rating is listed in the specs. That points to use inside protected equipment or an enclosure rather than direct outdoor or washdown exposure.
