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. 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. Derating may be needed under low input voltages. Please check the derating curve for more details.
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-100-48 for 48V industrial networking or control equipment?

Yes, it provides constant-voltage 48V output: 1.6A (76.8W) with convection cooling, or 2.1A (100.8W) with a 20CFM fan. It is suited to industrial or embedded equipment that is designed for 48V DC and operates within those limits.

Is this a good fit for 48V telecom or communications hardware inside a cabinet?

It can be a fit when the telecom or communications device requires 48V DC and draws no more than 1.6A with convection cooling (2.1A with a 20CFM fan). The 90-264VAC input range also supports use in systems intended for broad AC input conditions.

Can the EPP-100-48 power a 48V embedded or automation subsystem?

Yes, for a subsystem that calls for constant-voltage 48V input and stays under 76.8W total load with convection cooling (100.8W with a 20CFM fan). Its 48V, 1.6A/2.1A output is better aligned with lower-current 48V electronics than with heavier 48V loads.

Can I use the EPP-100-48 outdoors or in harsh exposed conditions?

The published operating temperature is -30°C to +70°C, with output derating at higher ambient temperatures (see the derating curve). However, no IP rating is listed, so it is better treated as a power supply for protected indoor equipment or enclosed systems rather than direct outdoor exposure.
