SCT013-030 Split-Core Current Transformer (0–30A, 0–1V Output)
Product Description
The SCT013-030 is a high-accuracy split-core current transformer (CT) designed for non-intrusive AC current measurement. Its clip-on structure allows quick installation without disconnecting wires, making it ideal for energy monitoring, automation systems, and protection circuits.
This model provides a voltage output (0–1V AC) and includes an internal sampling resistor, allowing direct connection to measurement circuits, data acquisition systems, and microcontroller ADC inputs.
The SCT013-030 is suitable for use in AC motors, lighting systems, air compressors, and general electrical monitoring applications.
Key Features
- Split-core, non-invasive design
- Measures AC current only
- Built-in sampling resistor (voltage output type)
- High accuracy and excellent linearity
- Safe isolation from high-voltage lines
- Easy clip-on installation
