Features:Analog Current Meter Module. Transformer can only sense ACThis electricity sensor is based on TA12-100 current transformer, which can transform AC signals of large current into small amplitude signals.You can use jumpers to select the parallel output of the output to adjust the range of analog values that are outputOn-board 3P and 4P connecting interface for current signal output can be easily connected with your MCU development boardOn-board precise miniature current transformerOn-board high precision amplifier with frequency compensation Specification:Transformation coefficient: Max 1000:1 Input current: Max. 5AOutput current: Max. 5mASampling resistor: Max. 200Working frequency: Max.20-20000 HzWorking temperature: -55~85 Dielectric strength: 6 KAC/1minInterface: 3PIN/4pinWeight: Approx.10g/0.4ozPackage list:1* Current Sensor Module
