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. 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. 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-100-48 for a 48V industrial control or communications load?

Yes, if the equipment requires a constant 48V DC source and draws no more than 2.2A or 105.6W. It is intended for 48V systems, so voltage matching is the key requirement.

Is the HRP-100-48 appropriate for a compact 48V embedded system?

It can be a fit for embedded 48V electronics that stay within 2.2A output current and 105.6W total power. The 159.0 × 97.0 × 38.0 mm form factor is also suitable where a compact power supply is needed.

Can this model power a 48V automation device from a wide AC input range?

Yes. The unit accepts 85-264VAC input and converts it to a constant 48V DC output, with up to 2.2A available on the output side.

Is the HRP-100-48 better for lower-current 48V loads than for high-current 48V equipment?

Yes. Its output is limited to 2.2A at 48V, so it is suited to lower-current 48V loads within 105.6W rather than heavier 48V systems that need more output current.

How does the HRP-100-48 compare with the other HRP-100 models?

The HRP-100 series includes 3.3V at 20A and 66W, 5V at 17A and 85W, 7.5V at 13.5A and 101.3W, 12V at 8.5A and 102W, 15V at 7A and 105W, 24V at 4.5A and 108W, 36V at 2.9A and 104.4W, and 48V at 2.2A and 105.6W. The HRP-100-48 is the highest-voltage listed version in the 100W family.

Can the HRP-100-48 be used outdoors or in harsh ambient temperatures?

The specified operating temperature range is -40°C to +60°C, which supports use across a broad temperature range. No IP rating is listed in the provided specs, so exposure to rain, dust, or washdown conditions should not be assumed.
