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

What output does the Mean Well EPP-150-24 provide?

This model provides a 24V DC output with a rated current of 4.2A. Its listed power rating is 100.8W, which matches its standard free-air convection rating.

Is the EPP-150-24 suitable for equipment used in industrial environments?

It is designed for embedded and industrial applications that need a compact open-frame AC-DC power supply. The unit supports operation from -30 to +70 degrees C (with derating per the derating curve) and includes overload, over voltage, and over temperature protection.

What input range does the Mean Well EPP-150-24 accept?

The power supply accepts a universal AC input range of 90 to 264VAC. It also supports 127 to 370VDC input, which helps it fit a wide range of OEM and equipment designs.

How compact is the EPP-150-24 for space-constrained designs?

This model uses a 4 x 2 inch compact form factor. Its listed dimensions are 101.6 x 50.8 x 29 mm, making it suitable where mounting space is limited.

Does the EPP-150-24 include efficiency and power-saving features?

Yes. It includes active PFC with a power factor above 0.95 at full load and reaches a typical efficiency of 93%. Those characteristics can help reduce wasted energy in always-on equipment.

Can this power supply deliver more than 100W?

This model is rated for 100W under free-air convection conditions, and up to 150W with 20CFM forced air. Buyers should evaluate the cooling conditions in the end equipment when comparing it with fixed 150W open-frame models.

Does the EPP-150-24 offer any auxiliary output or status indication?

Yes. It includes a built-in 12V / 0.3A auxiliary output and an LED indicator. The auxiliary output is intended for driving a cooling fan via the fan connector, which lets the unit reach its 150W forced-air rating.
