SCT-013 Split Core AC Current Transformer

The SCT-013 Split Core AC Current Transformer is a non-invasive, open-close type current sensor designed for accurate and safe AC current monitoring without the need to interrupt or modify existing electrical wiring. Available in 30A, 50A, and 100A variants, this sensor is an essential component for energy monitoring systems, smart home applications, power analysis tools, and industrial current measurement projects.

The split-core design allows the sensor to be clipped directly around a single current-carrying conductor, making installation effortless and completely non-destructive. The 30A and 50A variants feature a standardised 1V output signal, while the 100A variant delivers a 50mA output, catering to a broader range of measurement and logging applications. All variants are directly compatible with popular microcontrollers including Arduino, ESP32, and STM32.

Housed in a durable plastic enclosure with a secure locking latch, the SCT-013 ensures consistent core alignment and reliable readings over long-term use. Whether you are monitoring household energy consumption, building a smart energy meter, or developing an industrial power logger, the SCT-013 provides the accuracy and convenience your project demands.
