QI-50-V-485 Current Trasformer

TRMS AC/DC Current Transformer, 50A, 0-10V Output and RS485 Modbus

 The QI-50-V-485 is a direct and alternating current transformer, galvanically isolated from the measuring circuit.

The device is in function and appearance quite similar to a standard active CT, but capable of measuring DC and AC RMS.

The transformer is equipped with an RS485 serial output for Modbus RTU connection through which span and zero can be freely configured.

RMS AC/DC Current Transformer, 0...50 A, analogue and serial output, span settable via Dip-Switch or via RS485, DIN rail mounting.
