Open loop Hall Effect current sensors for high AC and DC current measurement with signal conditioning. 100 to 1000 ARMS True RMS across a DC to 6000 Hz bandwidth, covering both fundamental frequency AC and the full harmonic spectrum of SCR-controlled, VFD-driven, and switching power supply loads. Three output variants: DHR-C420 (4-20mA), DHR-C5 (0-5V), and DHR-C10 (0-10V).

External DC unipolar supply 20–50V; solid core; 1% accuracy; CE marked. Applied in smart grid monitoring, large motor and drive current measurement, SCR phase-angle and burst-fired load measurement, and high-current industrial automation.
