FL45 RJ45 Gigabit Ethernet Surge Protector 10/100/1000M

FL45 RJ45 Gigabit Ethernet Surge Protector 10/100/1000M

FL45-E1000 1000M Ethernet signal surge protector is designed by IEC61000-4-5 and ITU-TK20&K21 standards. It adopts multilevel protective circuit and the newest high-speed surge protection device which has quick response, low residual voltage output and excellent transmission performance. The interface is RJ45 which is easy to use and suit 10/100M/1000M Ethernet device protection, such as lightning protection for wireless AP, web cams, HUB, switch, router.

FL45-E1000 gigabit Ethernet signal lightning protector is designed and manufactured on the principle of discharge, limited current, clamping, stabilivolt. When signal wire gets an overvoltage and overcurrent shock, it will put lightning power or its jamming signal into the ground. Overvoltage restriction enables electrical equipment to operate safely within allowable range.

This product adopts metal housing and good sealing, which has anti-dust and anti-corrosion function. It adopts serials connection that can restrain high voltage pulse on the wire to prevent backend device from being damaged by lightning and industrial surge.
