HAZ
Compact current transducers for AC and DC currents from 4000 to 20000A.
HAZ - Current sensors
The HAZ current sensor family is exclusively designed for measuring DC, AC, or pulsed currents while ensuring galvanic isolation between the primary circuit and the secondary circuit.
Within the HAZ family, you have the option of signal conditioning or obtaining instantaneous outputs. These sensors operate effectively with a bipolar power supply of +/- 15V and feature secondary connections using the Fujicon F2023A connector (Terminals).
HAZ current sensors are built upon open-loop Hall effect technology, making them well-suited for a range of applications. They are versatile enough to be employed in both industrial and railway settings, including use in fixed installations and onboard trains and locomotives.
