RJ45 surge protector for POE++
Part Number: 581545
MJ8-POE-A/SD
- POE++ compatible
- Strong mounting for DIN-rail for vibration enviroments
- Gigabit Ethernet (Cat.5E)
- Shielded enclosure and connectors
- 2 kA discharge capability
- IEC 61643-21, EN 61643-21 compliance
MJ8-POE-A/SD is designed with more stronger mounting DIN-Rail bracket for fitting vibration environment like wind turbines.
This product protect sensitive data-processing equipment connected to a POE++ (Power over Ethernet) network from transient overvoltages, is deployed in signal network applications with data transmission speeds of 100 and 1000 Mbps.
The surge protector is housed in a shielded enclosure with high quality RJ45 shielded jacks.
The transient protection circuit is based on high energy gas discharge tubes (GDT) and a network of fast response silicon avalanche diodes (SAD) to achieve sharp clamping of very large surge events.
