ACtrms/DC Current transformer, 2-wire transducer, Qeed QI-300I

Configurable 300 / 150 ACrms or ±300 / ±150A DC ranges, Output 4-20 mA

Qeed QI-300I

is an AC/DC current transformer, galvanically insulated from the measured circuit. As for its operation and appearance it is very similar to a standard active TC, however, can measure DC and AC TRMS current. Qeed QI-300I is 4-20mA loop powered, so it does not need a direct power supply. It is the first Hall-effect type, loop powered current transformer / transducer with an accuracy of 0.5% on the market.
