ZMCT103E 40 Ampere Current Transformer – PCB Mounting is a small size 5A 2.5A Micro precision current transformer is the best for the purpose of the DIY project and industrial application, where we need to measure the accurate AC current with current transformer. This is an perfect choice to measure the AC current using Arduino/ESP8266/Raspberry Pi like an opensource platform.
In many electrical projects, engineer directly deals with measurements with few basic requirements like
- High galvanic isolation
- High accuracy
- Good Consistency
