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. Derating may be needed under low input voltages. Please check the derating curve for more details.
- 6. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
- 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 HRP-75-48 for 48V telecom or industrial network equipment?
It is suitable for 48V constant voltage equipment that stays within 1.6A and 76.8W. That makes it a fit for lower-power 48V telecom, communications, or industrial network loads that require a regulated 48V bus.
Is the HRP-75-48 appropriate for a 48V embedded control system?
Yes, if the system is designed for 48V constant voltage input and its total demand does not exceed 76.8W or 1.6A. The 85-264VAC input is also useful where the AC source can vary across different sites.
Can this model be used for small 48V automation loads?
It can support 48V automation devices as long as the combined load remains within 1.6A at 48V. The output can also be adjusted between 45V and 55.2V to match the load, while staying within the 76.8W rating.
How does the HRP-75-48 compare with the other HRP-75 voltage options?
The HRP-75 range includes 3.3V 49.5W 15A, 5V 75W 15A, 7.5V 75W 10A, 12V 75.6W 6.3A, 15V 75W 5A, 24V 76.8W 3.2A, 36V 75.6W 2.1A, and 48V 76.8W 1.6A. The 48V version keeps similar wattage to the 24V and 36V units but offers the highest output voltage and the lowest current in the HRP-75 group.
Can the HRP-75-48 be used in unheated or warm equipment spaces?
The rated operating range is -40°C to +70°C, with output derating at the upper end per the derating curve (-40°C start-up is possible with 230VAC input), so it covers very cold and very warm ambient conditions. The provided specs do not list an IP rating, so it should be treated as a protected-location power supply unless enclosure protection is confirmed separately.
