Test conditions and notes7
- 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. 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 )
- 5. 3.3V PF>0.92/230VAC, others PF>0.95/230VAC.
- 6. Derating may be needed under low input voltage. Please check the derating curve for more details.
- 7. 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 ELP-75-3.3 for 3.3V embedded processors or industrial logic boards?
Yes, this model is a constant-voltage 3.3V supply rated for 49.5W and 15A. It fits embedded processors, industrial logic boards, or digital electronics that require a regulated 3.3V source and stay within the 15A limit.
Is the ELP-75-3.3 suitable for powering 3.3V FPGA, MCU, or SBC-based systems?
It can be used for 3.3V FPGA, MCU, or SBC-based systems when the load is designed for constant-voltage 3.3V input. The available output is high current at 15A, with total power up to 49.5W.
Can this power supply support 3.3V industrial communication or control electronics?
Yes, for 3.3V communication, control, or data-processing electronics that need a stable 3.3V DC rail. The unit provides up to 15A output current, which is useful where lower voltage electronics draw comparatively higher current.
How does the ELP-75-3.3 compare with other ELP-75 models?
In the listed series, outputs include 3.3V at 49.5W and 15A, 5V at 75W and 15A, 12V at 75W and 6.25A, 15V at 75W and 5A, 24V at 75.6W and 3.15A, 36V at 75.6W and 2.1A, and 48V at 76.8W and 1.6A. This ELP-75-3.3 is the lowest-voltage option shown, with 49.5W output and 15A current.
Is the ELP-75-3.3 appropriate for outdoor use or temperature-sensitive environments?
The operating temperature range is specified at -30°C to +70°C, with load derating at higher ambient temperatures per the derating curve, so the unit is rated for a broad temperature window. No IP rating is included in the provided specs, so outdoor, splash, or dust-exposed suitability is not established by this data.
