Qeed QI-50-I

The QI-50-I is a AC/DC current transformer, galvanically isolated from the measuring circuit. The device is in the function and appearance very similar to a standard active TA, however, able to measure the DC component and AC TRMS. The transformer is powered 4-20mA current loop and therefore does not require a direct power supply. It ‘s the first Hall’s effect current transformer loop-powered with 0.5% accuracy on the market.
