Feature: 1. Applicable Signal: The surge protection device is suitable for signal lines, communication lines, remote control signals, telemetry signals and other equipment lightning protection. Such as RS232, RS485, RS422, etc. 2. Through Current Capacity: Our surge protective device has a large through current capacity, multi levels protection, low residual voltage between lines, rapid response time. 3. Basic Parameters: The nominal operating voltage of the surge protection device is 12V, the maximum continuous operating voltage is 15V, the nominal discharge current (8/20us) is 5kA, and the maximum through current capacity (8/20us) is 10KA. 4. Simple Wiring: Surge protective device integration, small size, simple wiring and easy installation, reducing the occupation of space. 5. Fast Semiconductor Protection Device: Our surge protector module built in fast semiconductor protection device nanosecond response speed. Specification: Item Type: Surge Protective Device Material: Flame Retardant PC Nominal Working Voltage (Un): 12V Maximum Continuous Working Voltage (Uc): 15V Nominal Discharge Current In (8/20us): 5kA Maximum Through Current Capacity (8/20us): 10KA Voltage Protection Levels Up: ≤40V Protection Grade: IP20 . Package List: 1 x Surge Protective Device Note: 1. Surge protector connected in series between the protected equipment and the signal channel.2. The input side of the surge protector (IN) and the signal channel connected to the output side (OUT) and the input side of the protected equipment connected, can not be reversed.3. Surge protector ground wire and lightning protection system ground line is reliably connected.4. This product does not require special maintenance, when the system work failure and suspicion of surge protector, you can remove the surge protector and then check, if restoring to the state before using the system back to normal, then the surge protector should be replaced.
