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 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 )
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-200-48 for a 48V industrial control panel or automation subsystem?

Yes, this model is a constant-voltage 48V supply rated for 144W and 3A with convection cooling, or 201.6W and 4.2A with a 10CFM fan, which fits 48Vdc control or automation loads within that range. Its wide 80-264VAC input also supports deployment in facilities with varied AC mains.

Is the EPP-200-48 suitable for powering a 48V embedded computer or industrial networking device?

It can be, provided the equipment requires a regulated 48V constant-voltage input and draws no more than 3A/144W by convection, or 4.2A/201.6W with a 10CFM fan. The compact 101.6 x 50.8 x 29.0 mm size can also matter where board-level space is limited.

Can this power supply run a 48V telecom or access-control load?

It is appropriate for 48Vdc loads that need up to 144W and 3A with convection cooling, or up to 201.6W and 4.2A with a 10CFM fan. Buyers should match the device's required DC voltage to the unit's fixed 48V constant-voltage output.

Is the EPP-200-48 rated for outdoor or harsh-environment use?

The provided specs show an operating temperature range of -30 degrees C to +70 degrees C, with output derating at higher temperatures per the derating curve. However, no IP rating is listed, so the provided data does not establish suitability for exposed outdoor, washdown, or wet locations.

How does the EPP-200-48 compare with other EPP series options?

This spec sheet covers only the EPP-200 series, so other EPP families are not listed here. Within EPP-200, the 48V model delivers 3A/144W by convection or 4.2A/201.6W with a 10CFM fan, while the 12V, 15V, 24V and 27V versions are rated 140.4W to 143.1W by convection and 200.4W to 202.5W with a fan.
