HAC
For the electronic measurement of currents: DC, AC, pulsed... with galvanic separation between the primary circuit and the secondary circuit.
HAC - Current sensors
The HAC family is composed of compact current sensors for AC and DC currents from 200 to 800A. They are designed for industrial applications.
These sensors benefit from instantaneous voltage output of +/- 4 V., a bipolar power supply of +/- 15 V and a bandwidth of DC 50 kHz.
HAC current transducers are based on the open loop Hall effect technology.
