The PHOENIX CONTACT CN-UB-70DC-6-BB is a coaxial surge protection device designed to safeguard sensitive electronic equipment from damaging voltage surges and transients. This device is specifically engineered for coaxial signal interfaces, offering a reliable and effective solution for protecting valuable infrastructure. It utilizes an N connector, female/female configuration, and provides voltage protection up to 650V. The device's robust construction and surge handling capabilities make it suitable for a wide range of industrial applications, including telecommunications, broadcast, and data transmission systems. Proper usage requires pairing with a transmitter unit to shut down in the event of a short circuit.
Note: To meet the discharge conditions for DC voltages, please note the following information: "The surge protective device should be used together with a transmitter unit, which shuts down in the event of a short-circuit."
