ZeroDT GB-1

ZeroDT GB 1

The protection of the ZeroDT GB-1 utilizes state of the art semiconductor devices, TBUs (Transient Blocking Units) in a hybrid circuit topology to provide Ethernet (10/100 BASE-T) and Gigabit Ethernet (1000 BASE-T) devices with carrier grade surge and lightning transient protection. The protector provides long-term system reliability by blocking the damaging transient energy to prevent damage yet remaining transparent to the data thruput of the line. The module has been tested to the Telecommunications Port Type 3 & 5, Level I & II Lightning Requirements as well as Severe Climatic Conditions as outlined in GR-1089-CORE so you can rest easy knowing your devices are well protected. The unit does not degrade with repeated usage. The low capacitance TBUs act as ‘ultra-fast disconnect switches’ — When an overvoltage situation is sensed on the line, the TBU acts to ‘disconnect’ the equipment, and the circuitry provides a path to Ground for the damaging energy to prevent it from reaching the equipment. As soon as the voltage on the line returns to normal levels, the unit returns to its original state and allows the communications to resume unhindered, while being ready for the next overvoltage event.
