Four small white rectangular PoE injectors with Ethernet ports and power cables

Ubiquiti Networks

Ubiquiti Networks POE-48-24W 4-pack 48V .5A 24W PoE injector

SKU CH-PAA0-ZT9HV

Four 48 V 0.5 A 24 W PoE injectors power compatible Ubiquiti devices and include surge, clamping and ground protection

  • Powers UniFi and airMAX gear with 48V .5A delivery
  • Four injectors included for multi-device deployments
  • 24W output matches spec for compatible Ubiquiti hardware
  • Built-in surge and clamping protection safeguards connected devices
  • Earth-grounded AC cable improves electrical safety

Four-pack 48 V PoE injectors

This pack contains four Ubiquiti Networks POE-48-24W injectors that deliver 48 V DC at .5 A for a total of 24 W per unit. They are designed to supply Power over Ethernet to compatible Ubiquiti hardware such as airFiber, airMAX, EdgeMAX, mFi, UniFi AP, UniFi Protect, UniFi LED and UFiber devices. Each adapter includes surge protection, clamping protection, maximum surge discharge and peak pulse current safeguards. An AC cable with earth ground is provided for safe installation.

Installers powering multiple Ubiquiti PoE devices

The four-unit bundle suits network installers or small ISPs who need to power several Ubiquiti access points, radios or cameras from a single purchase. It is not intended for buyers who need active 48 V .5 A 24 W PoE injectors with different voltage or current ratings, nor for those who require a single injector rather than a multi-pack. Users with non-Ubiquiti PoE equipment should verify compatibility before purchasing.

48 V .5 A 24 W output per injector

Each injector provides a fixed 48 V DC output at .5 A, yielding 24 W of power over the Ethernet cable. This specific voltage and current combination determines whether the adapter will correctly power a given Ubiquiti device, so match the requirement exactly to the target hardware’s specifications.

Questions about this item

How do I install the 48V .5A PoE injector and which step is often missed?

Connect the AC cable with earth ground to mains, link the LAN port to your switch, then run the PoE port to the device; the step often missed is securing the earth ground on the AC cable for surge and clamping protection.

What maintenance or replacement will the 24W PoE injector need later?

The injector has no user-serviceable parts; if surge protection components absorb a large event they can degrade, so replace the unit after a known lightning strike or if connected devices show intermittent power.

What limit appears first on the 48V .5A adapter under sustained load?

The hard limit is the 24W output rating; drawing more than .5A at 48V will cause the adapter to shut down or reduce voltage to protect connected Ubiquiti gear.
