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. Derating may be needed under low input voltages. Please check the derating curve for more details.
  5. 5. 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).
  6. 6. 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 EPP-150-12 for 12V PLC, relay, or control circuits?

Yes, if the automation hardware requires constant 12V DC and the total demand stays within 8.4A and 100.8W. It is a better fit for 12V control loads than equipment that expects 24V, 27V, or 48V.

Is the EPP-150-12 suitable for embedded PCs or industrial electronics that run on 12V?

It can be used for 12V embedded systems, industrial computers, or OEM electronics that accept a constant 12V input. The output capacity is 12V at up to 8.4A, and the input range is 90-264VAC.

Can this model power 12V monitoring, sensing, or test equipment?

Yes, for 12V instruments or support electronics that stay within the 100.8W limit. Buyers should confirm that the load matches the constant-voltage 12V output and does not exceed 8.4A.

How much 12V load can the EPP-150-12 support?

The rated output is 12V, 8.4A, and 100.8W with convection cooling, or 12.5A and 150W with a 20CFM fan. That makes it appropriate when the full connected 12V load remains at or below the figures for your cooling condition.

Is the EPP-150-12 meant for indoor or outdoor use?

Its operating temperature range is -30°C to +70°C, with derating at higher temperatures per the derating curve, but the listed specs do not show an IP rating. That means the product data supports protected indoor use rather than exposed outdoor placement.
