Sensor Mod.

CHB-1KC 2KC、3KC Closed-loop Hall Current Transducer

Description

The SENSOR Module CHB-1KC, 2KC, 3KC is a closed loop Hall current sensor to measure1000A…3000A DC, AC or pulsed currents with a galvanic isolation between the primary and secondary circuits. The aperture can be opened by a structure of a split core for easy installation.
