説明
AHKC-EKAA Split Core Open-loop Hall Effect Current Sensor
General
Hall current sensors are mainly used to isolate and convert AC, DC, pulse and other complex signals. After signals are converted according to the Hall Effect Theory, they can be directly acquired by AD, DSP, PLC, secondary instruments and other devices. Hall current sensors are widely applicable for acquisition and feedback control of current signals in the current monitoring, battery application, inverter, solar power management, direct current cabinet, DC motor drive, electroplating, welding, frequency converter, UPS servo control systems. They feature the quick response, wide range of measurement, high precision, strong overload capacity, good linearity and excellent anti-interference performance.
