LV (Voltage) Series

DC, AC pulse voltage measurements of 100 to 4000 VRMS nominal with galvanic isolation

LV Voltage Sensors

The LV sensor sensors offers versatility for a range of electrical measurements. Among these possibilities, the LV Voltage series specializes in voltage measurement.

Conversely, the LV Voltage sensors are meticulously crafted for the accurate measurement of DC, AC, or pulsed currents, all while ensuring robust galvanic isolation between the primary and secondary circuits.

These voltage sensors are designed for panel mounting and leverage closed-loop Hall effect technology, guaranteeing precision and dependability. This technology renders them exceptionally suitable for a wide spectrum of applications, encompassing both industrial and traction contexts.
