OUTDOOR GIGABIT POWER-OVER-ETHERNET (POE) SURGE PROTECTOR
CMJ8-POE Series
• 10/100/1000 Base T compatible• Shielded RJ45 connectors• 2 kA discharge capability• IEC 61643-21• UL497B
Characteristics
The CMJ8-POE is an outdoor PoE surge protector designed to protect sensitive data-processing equipment connected to a PoE (Power over Ethernet) network from transient over voltages.
The CMJ8-POE surge protector is deployed in signal networkapplications with data transmission speeds up to1000 Mbps and is equipped with high quality shielded RJ45 connectors.
The transient protection circuit is based on high energy gas discharge tubes (GDT) and a network of fast response silicon avalanche diodes (SAD’s) to achieve sharp clamping of very large surge events.
