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-75-48 for 48V industrial control or automation devices?
Yes, this is a constant voltage 48V power supply rated for up to 1.6A and 76.8W. It is appropriate for industrial and automation equipment that is designed for regulated 48V DC input within those output limits.
Is the ELP-75-48 a fit for 48V telecom or networking equipment that needs DC power?
It can be used where the equipment requires constant voltage 48V and the load does not exceed 1.6A or 76.8W. The 90-264VAC input is also useful where wide-range AC input compatibility is needed.
Can this model be used in compact cabinets for 48V embedded or industrial electronics?
Yes, the ELP-75-48 measures 175 x 60 x 27 mm as a PCB unit (195 x 68.5 x 33 mm with the optional case). That supports use in tighter equipment spaces as long as the 48V load stays within 1.6A and 76.8W.
Will the ELP-75-48 handle harsh temperature conditions indoors?
The operating temperature range is specified as -30°C to +70°C, with output load derating at higher ambient temperatures per the derating curve, which covers a broad temperature span for indoor electrical equipment. The provided specifications do not include an IP rating, so outdoor or wet-location suitability is not confirmed here.
How does the ELP-75-48 differ from the other ELP-75 series models?
The series includes 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. The ELP-75-48 is the 48V option, rated at 76.8W and 1.6A.
