The NetVanta PoE Protector/Injector provides detection, disconnect, overload, and voltage control protection fully compliant with IEEE 802.3af and 802.3at PoE specifications. It can provide power and data to an array of downstream PoE powered devices (PDs), such as IP telephones, wireless network access points, Bluetooth access points, security cameras, and IP print servers without the need for and expense of AC power outlets. Additionally, in situations where PoE is not available, the optional 48 V power supply can be used to inject PoE power.
The NetVanta PoE Protector/Injector also functions as a single port Ethernet surge protector where Ethernet cabling is exposed to external hazards.
The protector/injector minimizes the voltages and current levels transferred to the Ethernet or PoE port of the network equipment (e.g., switch) being protected, during electrical disturbances such as lightning storms or AC power induction/cross that occur on the device side (phone, camera, etc). This allows the PoE or Ethernet port of the switch to continue functioning properly and in most cases prevents permanent damage. Additionally, the protector/injector protects itself and the Ethernet port from becoming a fire or fragmentation hazard as a result of lightning or AC power cross events.
A significant advantage of the protector/injector is it does not require a ground connection. Protection is accomplished by high voltage isolation >6kV impulse.
