Automation system required various sensors and actuators to operate. Those sensitive sensors and components often damage and malfunction due to the surge induced by lightning strikes occurrence or other phenomena. In order to protect against such damages, PROMOV TD1-13 Series signal level SPD comes with various voltage signal protection range from 5 VDC to 130VDC.  TD1 signal level SPD has very low internal resistance which allow the system to have minimum voltage drop in between the SPD. 

TD1 series SPD has a compact design with only 9mm thick which can fit into various panel with minimum space consumption. On the other hand, it is suitable in various field from normal operational system to 24 hours not stop operational system because it comes with hot pluggable (signal interruption) and not hot pluggable (no signal interruption) feature. Furthermore, the SPD has red LED indicator to indicate the status of the SPD.
