HPE R3K00A – 12 V DC 48 W AC/DC Desktop Adapter
Overview
The HPE R3K00A is a desktop style AC to DC power adapter built for network engineers who need to power Aruba/HPE access points or other compatible networking gear without relying on PoE. This adapter outputs 12 V DC and supports up to approximately 48 W of power output (with some datasheets listing 36 W depending on region) for devices that require a 12 V input and a barrel-type 2.1/5.5 mm connector. For instance, when deploying indoor APs in an environment where PoE injection isn’t available or you prefer using a dedicated DC adapter, the R3K00A gives you a tested and vendor-approved power supply option.
Key Features
- 12 V DC output suitable for Aruba/HPE indoor APs (adapter model AP-AC2-12B) or other compatible devices.
- Up to ~48 W (or 36 W depending on region/variant) power delivery—sufficient for small network devices that don’t use PoE.
- Desktop “brick” form factor with integrated AC input, barrel 2.1/5.5 mm output connector—easy drop-in for wiring-closet or wall-mount deployment.
- Type-B plug variant—ensure regional AC input compatibility (100-240 V AC input typically).
- Ideal for installations where PoE budgets are constrained or when powering compact network gear separately rather than via switch PoE.
