The QI-50-I is an AC/DC current transformer which is galvanically isolated from the measuring circuit. The function and appearance of this device are very similar to a standard active CT, however it is able to measure the DC component and AC TRMS.
The transducer is loop-powered with current 4-20 mA so needs no direct power supply. It is the first loop-powered Hall effect transformer with 0.5% accuracy on the market.
AC/DC loop-powered current transformer TRMS, 0…50 A bipolar, analogue output 4…20 mA on loop, range set by dip-switch, ready for both vertical and horizontal DIN rail mounting.
