Description

The NT68167HFG is a closed loop current sensor designed to measure AC, DC, and impulse currents over a wide range. It is based on the principles of the Hall effect and the null balance or zero magnetic flux method (feedback system). The sensor core constantly maintains zero magnetic flux, and the output current is a measurement of the primary current reduced by the number of secondary turns. It can measure currents up to 1200 amps and offers a high level of electrical isolation between primary and secondary circuits. The NT68167HFG is compact and lightweight, making it an ideal choice for various applications.
