Modbus Current transformer

General Description

The QI 300 V RS485 from Qeed is an AC and DC current transformer with a Modbus RS485 and 0-10V dc output. The range is selectable between 150 and 300 Amps with a 12 to 30 Vdc power supply, and maximum consumption is 20mA. The output is isolated from the input up to 3000V. The unit can measure AC TRMS and DC with bipolar direction.
The baud rate, address, measuring range and the AC/DC setting can be set up with the aid of the DIP switches or the free software available on our website. The Current transformer can be mounted on DIN rail or screws.
