Spike and Noise Suppressor

The SN-1 is a bi-directional Spike and Noise Suppressor. Spike and Noise protection are both important for protecting sensitive electronics. Voltage spikes can damage electronics, while the RFI Noise can cause electronic controls to malfunction. The bi-directional feature allows the SN-1 to be used for both AC or DC without the worry of the correct polarity. Fig 2 shows how the SN-1 protects against lightning strikes by connecting the SN-1 between the control input you are protecting and Ground. Due to the high frequency noise filter inside, it is not recommended for lightning protection on data transmission lines or other high frequency applications.
