CM3A 500 H00
Product Description
Product Overview
The CM3A H00 SERIES is a closed-loop (compensated) Hall Effect current sensor designed for the electronic measurement of DC, AC, and pulsed currents. It provides galvanic separation between primary and secondary circuits, featuring very good linearity, high accuracy, and low offset drift over temperature. The sensor is housed in an insulating plastic case recognized according to UL 94-V0 and offers no insertion loss.
