Product SPD S-FLT-2D-5.Ex

S-FLT-2D-5.Ex

This SPD limits inducedt ransients 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，PROFIBUSDP，CAN ect.
