Reliable protection, easy to install and a compact package make the DLP-3.92 an ideal protection choice. Designed for use on 10BASE-T networks, the unit will prevent costly downtime of sensitive networks by protecting NIC (network interface cards) hubs and relays. Units are virtually invisible to the network and will not affect data rates. The DLP-3.92 responds in nanoseconds to an overvoltage and instantly diverts harmful surge currents away from sensitive equipment. Units install in minutes.
