48V Passive PoE Injector with Surge and ESD Protection for Ubiquiti Devices
The Ubiquiti POE-48-24W is a 48-volt, 24-watt passive PoE injector that powers Ubiquiti devices over a single Ethernet cable. It accepts 120/230V AC input and delivers 48V DC at up to 500 mA to the connected device through the data cable, eliminating the need for a separate power outlet at the device location.
The injector includes built-in surge protection, clamping protection, and an earth-grounded AC cable to guard against electrostatic discharge (ESD), which is the leading cause of outdoor device failures. For outdoor installations using airMAX, airFiber, or UniFi devices, the grounded PoE adapter is the first line of defense against lightning-induced surges traveling down the Ethernet cable.
Where the POE-48-24W Fits
- Outdoor wireless links and access points (airMAX, airFiber, UniFi AP) where the device mounts on a pole or rooftop and needs both power and data delivered over a single cable run from indoors
- Surveillance cameras and edge devices (UniFi Protect, U Fiber) in locations without a nearby power outlet, where pulling a separate AC line is impractical
- Replacement or spare injector for any Ubiquiti device that shipped with a 48V/24W PoE adapter and needs a backup or additional unit for a second installation
What the POE-48-24W Delivers
- 48V DC output, 24W max: Powers any Ubiquiti device rated for passive 48V PoE at up to 500 mA. One cable carries both data and power.
- Surge and ESD protection: Built-in surge clamping and peak pulse current protection. Earth-grounded AC input helps dissipate static buildup from outdoor cable runs.
- Universal AC input: Accepts 120V or 230V AC for worldwide use without a voltage selector or separate adapter.
- Pass-through Ethernet: One RJ45 input (from switch/router), one RJ45 output (to powered device). Transparent to network traffic.
