Nextek’s SurgeGuard K-Series is based on a multiple gas discharge tube design with serviceable replacement elements. The PTR7AF7AFxxK arrestors measure 119mm x 45mm, have 7-16 female to 7-16 female connectors, and can deliver a maximum of 50kW of RF power at a maximum through-current of 25A.The K-Series products can use a range of 1.4kV to 3.5kV gas discharge tubes and have a nominal impedance of 50W. Additional specifications include excellent lightning transient protection performance (125,000AMPS!), low return loss (VSWR) of 1.05 typical, and Insertion Loss (IL) of only 0.01 typical. All SurgeGuard products are considered “military grade” and are designed to be both waterproof and dustproof (IP68 Standard). The robust SurgeGuard K- Series provides a 250x multiple strike capability @ 10kA and a 125kA (8 x 20μs) one time surge capability.The K- series of lightning arrestors are currently available directly from Nextek.
