FHS AH-600

FHS AH-600 is a coreless current sensor. It is an open loop field sensor, a surface-mounted device based on the hall effect principle. This device uses an Integrated Magnetic Concentrator combined with improved sensitivity, offset, and temperature stress compensation allowing high accuracy and low noise current sensing. It is highly suitable for DC, AC, pulsed, and mixed current measurements with 160KHz bandwidth and fast response time ≤ 2µs. The contactless current sensing solution allows no additional power losses and high dielectric insulation between the primary circuit and transducer electronics. It removes the need of an external magnetic core, offers flexibility in a compact design, and is a perfect solution for the current measurements through a conductor as PCB trace. Typical applications include small drives, BMS, motor control, UPS, HVAC, white goods, PCB track current sensing.
