POE-ESA-20R

Twenty Port 10/100 PoE Surge Arrester

POE-ESA-20R

Twenty port 10/100 Ethernet (IP) surge arrester with a 10KA rating in an industrial 19inch rack mount enclosure, providing the perfect blend of premium performance with ease of installation. The POE-ESA-20R overs protection at both the low-end and high-end; the low-end protection is via fast responding TVS (Transient-Voltage-Suppression) diodes, and the top-end protection is via GDT (Gas-Discharge-Tubes). The POE-ESA-20R needs an electrical earth connection onto which the surge energy is safely discharged.

Features:

Warning!   As both ends of the data communication cable need protection, this may introduce resistively coupled transients in your system. Try our new Surge Blocking Protectors and avoid resistively coupled transients in your system.

Resistively coupled transients cause most of the lightning damage to electronics and electrical equipment. These transients are caused by a difference in potential between two connected electrical earth points.
