Open-loop Hall Effect current sensors for high AC and DC current measurement with integrated signal conditioning. 100 to 1000A RMS True RMS across a DC & 20 to 6000 Hz bandwidth, covering both fundamental frequency AC and the full harmonic spectrum of VFD-driven, SCR-controlled, and switching power supply loads. Three output variants: DHR-C420 (4–20mA), DHR-C5 (0–5V), and DHR-C10 (0–10V); large aperture accommodating cables up to Ø32mm; panel mounting; UL94-V0 insulating plastic case; no insertion losses.

Applied in VFD and SCR controlled load monitoring, switching power supply and electronic ballast input measurement, smart grid current monitoring, and high-current industrial automation where True RMS accuracy is required across distorted waveforms.
