Product Overview
The CHIPSENSE CS3A P00 Series are closed-loop (compensated) Hall Effect current sensors designed for the electronic measurement of DC, AC, and pulsed currents. They provide galvanic separation between primary and secondary circuits, featuring a UL 94-V0 insulating plastic case. These sensors offer high accuracy, very good linearity, low offset drift over temperature, and no insertion loss, making them suitable for a wide range of industrial applications.
