Test conditions and notes6

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
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. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltages. Please check the derating curve for more details.
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. 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-150-48 for a 48V industrial controller or PLC load?

Yes, if the controller requires a constant 48V DC supply and stays within 2.1A and 100.8W. This model is a constant voltage power supply rated at 48V output.

Is the EPP-150-48 suitable for embedded 48V electronics inside a compact machine?

It can be a fit for compact embedded equipment that needs 48V DC and does not exceed 100.8W. Its 101.6 x 50.8 x 29.0 mm size and 0.2 kg weight support use in space-constrained equipment.

Can this power a 48V automation module or sensor hub?

Yes, for 48V automation loads that draw no more than 2.1A total with convection cooling, or 3.125A with a 20CFM fan. The supply provides constant 48V output, so it is intended for equipment designed for fixed-voltage DC input.

Is the EPP-150-48 appropriate for indoor or outdoor equipment?

The operating temperature range is -30°C to +70°C, with derating at higher temperatures per the derating curve. However, no IP rating is listed in the provided specs, so outdoor or wet-location suitability is not established by these specs alone.
