Loop Powered Current transformer

General Description

The QI 300 I from Qeed is an AC and DC current transformer with a 2 wire 4-20mA output. The range is selectable between 150 and 300 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 TRMS 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.
