The HCS-C series of Panel mounted, Closed-loop, Hall Effect current sensors are designed for applications requiring the measurement of AC current, DC current and DC current pulses. The closed-loop design incorporates a second magnetic field used to offset the primary conductor magnetic field. The zeroing of the magnetic flux provides a highly accurate representation of the primary conductor current.
Features:

• Primary Conductor opening – 20mm (0.98″)
• Contact-less, non-intrusive current sensing.
• DC current, DC pulse and AC current measurements.
