The QI 400 I from Qeed USA is an DC loop powered current transmitter with a two-wire 4-20mA output. The range is selectable between 200 and 400 Amps with a DIP Switch. The power supply is 11 to 30 Vdc power supply, and maximum consumption is 3.5mA. The output is isolated from the input to 3000V. The unit can measure AC True RMS and DC with bipolar direction. Using the bipolar function means the zero is 12 mA. The Hall effect current transformer has 0.5% full-scale accuracy.
The current transformer can be mounted on a DIN rail or screws and can be mounted horizontally or vertically. There is an LED power indication.
