The E683x series of Rogowski flexible rope style current transducers (CTs) provide secondary AC voltage proportional to the primary (sensed) current. For use with E5xxxA and E2x series power meters, the E683x series CTs provide a cost-effective means to transform electrical service amperages to a voltage compatible with monitoring equipment. The flexible core makes it easy to fit in tight enclosures. These products provide reinforced insulation between the sensed conductor and the output leads. The E683x series works exclusively with the E2x and E5xxxA power and energy meters and is a U018 equivalent. These meters have a built-in power supply and integrator, so CT connection is fast and simple.
