Acrel BR-Series Flexible Rogowski Coils deliver safe, wide-range AC current sensing from 0.1 A up to 500 kA. The lightweight, IP65-rated loop simply snaps around busbars or cables without disconnection, eliminating CT saturation and open-circuit hazards. Exceptional linearity, high bandwidth and minimal position error guarantee accurate power-quality, harmonic, ripple or transient capture when paired with power analyzers, loggers or portable meters. Custom lengths and diameters fit tight panels, large furnaces, welders or retrofits. Zero power draw, DC 4-20 mA / 200 mV outputs and immunity to stray fields make BR coils the go-to choice for energy audits, arc-fault studies and high-frequency inverter monitoring.
