This Ubiquiti Networks PoE adapter, POE-48-24W, is a 48VDC 0.5A injector for use with various airMAX and UniFi products. 

Ubiquiti PoE Adapters provide a variety of features to help protect your PoE devices:

• Surge protection
• Clamping protection
• Maximum surge discharge
• Peak pulse current
• AC cable with earth ground

Electrostatic discharge (ESD) is the leading cause for outdoor device failures. You can effectively protect against ESD damage using a grounded Ubiquiti PoE Adapter, TOUGHCableTM, and TOUGHCable Connectors.
