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,
TOUGHCable™, and TOUGHCable Connectors.
