The HBC-LA series Hall effect current sensor is based on the Hall effect measurement principle, providing electrical isolation between the primary and secondary circuits. It accurately measures DC, AC, or pulse currents with a measuring range of 0-100A. The product offers a rated output current of 25mA±0.5% or 50mA±0.5%. It provides 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.
Attention:
- Is is positive when Ip flows in the direction of the arrow.
- Temperature of the primary conductor should not exceed 100 ℃.
- Dynamic performance are test with a single bar completely filling the primary hole.
- The primary turns round on the top of the sensor to perform best magnetic clutch
Features:
- Operating currents: 0 to 100A
- Rated output current: 25mA±0.5%, 50mA±0.5%
- Mount easily
