QI-50-I

Current Transformer AC/DC  TRMS  LOOP POWERED

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.

The QI-50-I has two dip-switches through which you can set the scale to 25 or 50A and select the monopolar or bipolar (see charts), the yellow led near the terminal will indicate the presence of the power supply. If you are using bipolar function on AC current, the value read will be 0 A (12 mA) because you are reading the average value.

Any changes made by dip-switch required to switch off the power supply. It’s a safety condition in order to prevent any manumission on the device.

MOUNTING:

The current transformer QI can be mounted in any position (see photo below), horizontal or vertical mounting, horizontal or vertical through the two hooks for DIN rail included in the box.

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.
