QI-300-I

CURRENT TRANSFORMER AC/DC LOOP POWERED

The QI-300-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 RMS. 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.

DIN rail mounting instructions:

To mount the hooks on QI. If you want to mount horizontally, use the flexibility of hook to catch into prepared by pressing the center of the clip. For vertical mounting, slide the hooks into the slots, external holding the two tabs on the clip . Fig. 6 For mounting on DIN rail horizontally, once hooked on the bottom, push with both hands. For vertical mounting on DIN rail, once hooked on the bottom, push with both hands on the hooks. To release from DIN rail, use a screwdriver and lever up to release the fins.

CAUTION: Magnetic fields of high intensity can vary the values measured by the transformer. Avoid installation near permanent magnets, electromagnets or iron masses that induce strong changes in the magnetic field. If any irregularity recommend reorient or move the transformer in the area most appropriate.
