Features 1、Analog Current Meter Module. Transformer can only sense AC 2、This electricity sensor is based on TA12-100 current transformer, which can transform AC signals of large current into small amplitude signals. 3、3-wire electronic block interface, input 5V - GND. S pin is the output analog voltage value. 4、You can use jumpers to select the parallel output of the output to adjust the range of analog values that are output 5、On-board 3P and 4P connecting interface for current signal output can be easily connected with your MCU development board Features: Analog Current Meter Module.
