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.
