LV (Current)

Suitable for measuring nominal voltages from 100 V to 2500 V

LV (Current) - Transducers

The LV sensor family provides versatility for various electrical measurements. Within this family, the LV Current series is specialized in current measurement and is engineered to excel in both industrial and railway environments.

LV Current sensors are specifically designed for precise measurement of DC, AC, or pulsed currents while maintaining galvanic isolation between the primary and secondary circuits. To perform voltage measurements, the user selects an external resistor, R1, which is then installed in series with the primary circuit of the transducer, allowing for a current proportional to the measured voltage.

These current sensors are intended for panel mounting and rely on closed-loop Hall effect technology, which ensures accuracy and reliability. This technology makes them exceptionally well-suited for a wide range of industrial applications.
