Product SPD KS-FLM-2-24

KS-FLM-2-24

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 pressure transmitter, valve positioner, electrical converter, flowmeter, solenoid valve and other field instruments ect.
