CHK-100R、200R、400R、600R、800R Open-loop Hall current sensor 

Description

The SENSOR Module CHK-R is an open loop Hall current sensor to measure 100A…800A 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.
