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. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: HRP-150-3.3/-5/-7.5/-12/-15)
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-150-48 for 48V industrial control or communications equipment?

Yes, this is a constant voltage 48V power supply rated for 158.4W and 3.3A. It is suited to 48V industrial, control, or communications equipment that operates within that output range.

Is the HRP-150-48 suitable for 48V automation or network devices in a control cabinet?

It can be used for 48V DC equipment in enclosed industrial systems where the total load does not exceed 3.3A or 158.4W. The universal 85-264VAC input also helps when the AC source varies by region or facility.

Can this model power a 48V embedded or telecom-style DC bus?

It is appropriate for regulated 48V DC applications that need up to 3.3A. That makes it a practical option for embedded or communications hardware designed around a 48V constant voltage input.

Is HRP-150-48 a good choice when higher voltage and lower current are needed?

Yes, within the HRP-150 range this version provides the highest listed output voltage at 48V with a 3.3A rating. It is intended for loads that need 48V constant voltage rather than higher-current low-voltage rails.

Can the HRP-150-48 be installed in outdoor environments?

The operating temperature range is -40C to +70C, with output derating at higher temperatures per the derating curve. However, no IP rating is listed, so it is better suited to protected indoor enclosures or sealed systems rather than direct outdoor exposure.

How does HRP-150-48 compare to the other HRP-150 outputs?

The HRP-150 family offers 3.3V at 99W and 30A, 5V at 130W and 26A, 7.5V at 150W and 20A, 12V at 156W and 13A, 15V at 150W and 10A, 24V at 156W and 6.5A, 36V at 154.8W and 4.3A, and 48V at 158.4W and 3.3A. The 48V model has the highest output voltage and the lowest current rating in that group.
