48V 50W Type-C power adapter

This HPE R3K01A adapter delivers 50 watts at 48 volts through a USB Type-C connector. It is an AC-to-DC power supply intended for compatible Aruba networking equipment. The unit ships new in a black and silver finish.

Suits Aruba devices needing 48V input

Network administrators replacing a lost or failed 48-volt adapter for supported Aruba hardware will find this match the required voltage and wattage. Installations that require a different voltage, a higher wattage rating or a barrel-style connector should look at other models.

48 volt output requirement

The single specification that decides compatibility is the 48 volt DC output; the connected device must be rated for exactly this voltage. Supplying 48 volts to hardware designed for a different level can cause damage or prevent operation.

Questions about this item

Will the Type C connector on this 50 W adapter wear out and need replacement?

The Type C connector is rated for thousands of insertion cycles; under normal office use it should last the life of the Aruba device it powers.

What is the first limit reached when the adapter runs continuously at 48 V and 50 W?

The 50 W output ceiling is the hard limit; sustained loads above that will trigger the built-in over-current protection.

How much heat and fan noise does the 50 W unit produce during all-day operation?

The adapter uses passive cooling, so it generates only warm surface temperatures and zero audible fan noise.
