Fig. 1: KL9540 Surge filter terminals for field supply The KL9540-0000 surge filter terminal contains an overvoltage filter for the field supply. The filter protects the components from line-bound surge voltages that can occur due to high-energy disturbance variables such as switching surges at inductive consumers or lightning strikes at the supply lines.
The use of such overvoltage filters is stipulated by the ship classification organizations in shipbuilding and on/offshore applications in which GL certification is required. The KL9540-0010 is intended in particular for the protection of analog terminals; the standard variant KL9540 for digital terminals.
