SK-7L01 Lighting Arrester
Shanghai Shenkai
SK-7L01 Lighting arrester is able to solve the problem that existing measures of lighting-proof could not effectively deal with effect of sensor data acquisition and processing system by lighting in lightning-prone area. It has effect of inhibition and protection to lighting impulse which is introduced from external lighting to sensor. It’s an effective and reliable way to ensure sensor data processor and the computer to work properly. Therefore, lighting arrester has provided a guarantee for the quality of CMS data acquisition and processing system. In addition, indicator of arrester real-time working status makes user more intuitive and easy to use and also provides an effective means to deal with system failure.
