The HBC-LAP series closed-loop Hall effect current sensor uses a closed-loop (compensation) principle, providing electrical isolation between the primary and secondary circuits. It accurately measures DC, AC, or pulse currents with a measuring range of 0-200A. The product has a supply voltage of ±12V to ±15V (±5%) and a rated output current of 100mA±0.5% or 125mA±0.5%. It offers high accuracy and easy installation. Dynamic performance testing uses a single bar fully filling the primary hole, with the primary wire wound around the top of the sensor for optimal magnetic coupling. It is widely used in welding power supplies, battery-powered applications, AC variable speed drives, servo motor drives, switching power supplies, UPS, and DC motor drive static converters.
