Bourns, Inc announced its latest series of TBU (Transient Blocking Unit) circuit protection devices for high speed protection of communications ports. The devices are said to be the industry’s first electronic current limiters (ECLs) designed to tolerate AC mains power contact without circuit damage. Designated the Bourns TBU DT-Series, the circuit protection device family provides desirable protection against faults caused by short circuits, AC power cross, induction and lightning surges. These fast-reacting protectors do not alter the signal performance of high speed communication ports. The new Bourns TBU devices are appropirate for Ethernet ports used in outdoor applications such as security systems, PV panels and service kiosks. The series features eight models and offers continuous AC voltage ratings up to 425 Vrms and nominal trigger currents ranging from 150 mA to 750 mA.
