The Patton EPG Token Ring surge protectors guard 802.5 networks against data loss and hardware damage caused by data line transients. Working in conjunction with AC surge protectors, these devices intercept harmful data line transients and divert them safely to chassis ground before they can damage delicate NIC components. Sophisticated solid state circuits allow our Token Ring protectors to take hit after hit without degrading, and to protect transparently without hindering network performance. Type 1, Type 3 or IBM Data Connector versions are available.
