KS-FLM-2-5.Ex

This SPD limits induced transients of different origin (lightning stroke, switching impulse, etc.). This is achieved by diverting the transient current to ground and limiting the signal line voltage to a safe level for the duration of the surge. It can be applied to 2 wire RTD, TC  ，RS-485, MODBUS, PROFIBUS-DP, CAN and other products.
