Overview
The Non-invasive AC Current Sensor Transformer 50A (SCT-013) is a split-core current transformer designed for safe, accurate AC current measurement without disconnecting wires. Its compact, lightweight construction and high-accuracy sensing make it an excellent choice for home energy monitoring, power meters, developer projects, and industrial energy management systems.
Key Features
- Non-invasive split-core design for fast installation around conductors without interrupting the circuit.
- 50A capacity suitable for medium to large electrical loads and general-purpose AC current monitoring.
- High accuracy sensing to provide reliable current data for power measurement and energy analysis.
- Safe non-contact measurement that minimizes electrical hazard risk during installation and use.
- Compact and durable construction for use in residential, commercial, and light industrial environments.
Applications
- Home energy monitoring and identifying energy-hungry appliances.
- Integration with power meters and energy management systems.
- AC power monitoring in panels, distribution boards, and equipment racks.
- Current measurement for microcontroller, Arduino, and IoT projects.
- Industrial and commercial monitoring where non-invasive sensing is preferred.
Benefits
- Safe and simple installation: Split-core clamp makes mounting fast and tool-light without cutting or disconnecting wires.
- Improved energy efficiency: Real-time current data helps identify usage patterns and reduce electricity costs.
- Versatile integration: Works with a wide range of monitoring systems and development boards.
- Reliable performance: Built for repeated use in varied environments while maintaining measurement consistency.
How to Install and Use the SCT-013
- Turn off or follow appropriate safety precautions before accessing the wiring area.
- Open the split-core sensor and place it around a single phase conductor (do not clamp around a cable containing multiple conductors).
- Close the core until it latches securely and route the output lead to your monitoring device or ADC input through any required burden resistor or interface circuit.
- Power your measurement system and calibrate readings as needed against a known load to ensure accurate readings.
- Use the real-time output for energy monitoring, logging, or control actions in your energy management system.
Compatibility and Integration
The SCT-013 is compatible with power meters, data loggers, microcontrollers, Arduino boards, Raspberry Pi (with ADC), and IoT gateways when paired with the appropriate signal conditioning or burden resistor. It is recommended for AC systems and is not intended for DC current measurement.
Technical Notes and Safety
- Designed for AC current measurement up to 50 A.
- Non-contact measurement reduces electrical shock risk, but always follow local electrical codes and safety practices.
- Ensure the sensor is placed around a single conductor for correct readings; clamping around multi-conductor cables will yield incorrect results.
- For best accuracy, calibrate the sensor in your specific system and account for any burden resistor or input circuitry.
Why Choose the SCT-013?
The Non-invasive AC Current Sensor Transformer 50A (SCT-013) combines safety, accuracy, and ease of installation in a compact package. Whether you are a homeowner aiming to reduce energy bills, an electrician monitoring loads, or a developer building smart energy solutions, the SCT-013 offers a reliable way to measure AC current without intrusive wiring changes.
