What is CT sensors Split core current transformers (CTs) are a type of sensor designed to measure alternating current, particularly useful in gauging total electricity consumption or production. Highly suitable for DIY projects, this type of CT can be quickly installed on either the live or neutral wire without any need for dangerous high voltage work. Applications Suitable for the current measuring Monitoring and protection of AC motor Lighting equipment Air compressor Specifications Input Current: 0~30A AC Output Mode: 0~1V Non-linearity:2-3% Build-in sampling resistance(RL): 62Ω Turn Ratio: 1800:1 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-013-030 Datasheet CT Senors - Introduction CT Sensors - Interfacing with an Arduino CT Sensors - How to build an arduino energy monitor
