This isolated shunt based current measurement unit enables high accuracy current measurement without the use of Current Transformers (CT). The isolation is achieved through the use of AMC1304 that incorporates both high voltage isolation as well as the Delta-Sigma Modulator. This solution eliminates the need for the CT which customers value due to the decrease in board size, reduced product weight, mitigation of cross talk and EMI in the system, and potentially increases product life through lower mechanical issues by replacing the CT with a shunt.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
