The Ubiquiti POE-48-24W is a Power over Ethernet (PoE) adapter or injector. Its main purpose is to supply both power and network data to a device using a single Ethernet cable. This particular model is designed to power devices that require a higher voltage.

Key Features and Specifications

• Output Voltage and Power: It provides 48V DC at 0.5A, for a total power output of 24W. This makes it compatible with various Ubiquiti products that need this specific voltage, such as certain UniFi access points and other networking equipment.

• Gigabit Ethernet (Optional): The model you're referring to, the POE-48-24W, comes in two versions:

  • POE-48-24W: This version has a 10/100 Mbps Ethernet port.

  • POE-48-24W-G: This is the Gigabit version which supports speeds of up to 1000 Mbps (1 Gbps).

• Safety Features: It's built with multiple protection features to safeguard connected devices from electrical surges. These include surge protection, clamping protection, and earth grounding.

• Compatibility: This adapter is a passive PoE injector, meaning it doesn't negotiate power with the connected device like an active PoE (802.3af/at) standard would. It's crucial to ensure your device is compatible with 48V passive PoE before using this adapter, as using it with an incompatible device could cause damage.

• Physical Design: The adapter is a compact, plastic-enclosed unit intended for indoor use. Some models are wall-mountable, which helps with cable management and installation.
