What is CT sensors? CTs are crucial for measuring AC and are popular for tracking whole-building electricity consumption. The split core model, such as the one pictured, is excellent for DIY applications as it can be simply clipped onto the live or neutral wire without requiring any high voltage electrical work. Applications Suitable for the current measuring Monitoring and protection of AC motor Lighting equipment Air compressor Specifications Input Current: 0~100A AC Output Mode: 0~50mA Non-linearity: ±3% Turn Ratio: 100A:0.05A Resistance Grade: Grade B Work Temperature: -25°C ~ ﹢70°C Dielectric Strength(between shell and output): 1000V AC/1min 5mA Leading Wire in Length: 1m Open Size: 13mm x 13mm Documents SCT-013 Series SCT-013-000 Datasheet CT Senors - Introduction CT Sensors - Interfacing with an Arduino CT Sensors - How to build an arduino energy monitor
