The ABB ES500-9661 is a high-performance closed-loop Hall effect current sensor designed for the precise electronic measurement of DC, AC, and pulsed currents. Part of the reliable ES500 series, this transducer provides excellent accuracy and linearity with galvanic separation between the primary circuit (high power) and the secondary circuit (electronic circuit). Its robust construction makes it ideal for demanding industrial applications such as variable speed drives, inverters, power supplies, and battery management systems, ensuring accurate monitoring and control.
