Open Loop Current Sensor AC/DC Current Transducer K3n Series Hall Effect Sensor

Product Description

K3N series hall effect current sensor is an open loop device based on the measuring principle of the hall effect, with a galvanic isolation between primary and secondary circuit. It provides accurate electronic measurement of DC, AC or pulsed currents.
