SCT013-80-333

Current Sense Transformers Overview

The SCT013-80-333 is a split-core current transformer manufactured by PowerUC Electronics, designed for non-intrusive AC current measurement. It features an 80 A primary current rating with a secondary output of 0.333 V at full load, ensuring a precise 1% accuracy class. The device operates within a frequency range of 50 Hz to 1 kHz and utilizes a floating in-line installation method. Constructed as a toroidal sensor, it allows for easy clamping around conductors without circuit interruption. The component is RoHS compliant and rated for Moisture Sensitivity Level 2.

Current Sense Transformers Feature Summary

• Split-core design enables rapid installation on existing busbars or cables without disconnecting the power line.
• Provides isolated analog voltage output proportional to the measured AC current for direct interfacing with data acquisition systems.
• Maintains high measurement precision across standard utility frequencies up to 1 kHz.

Current Sense Transformers Applications

• Energy monitoring and smart metering systems
• Industrial equipment current sensing and protection circuits
• Building automation and HVAC system control

Current Sense Transformers Procurement Notes

Verify that the specific SCT013-80-333 designation corresponds to the 80 A / 0.333 V variant from PowerUC Electronics. Confirm the physical aperture size matches the target conductor diameter. Ensure the application environment remains within the specified 50 Hz to 1 kHz operational bandwidth to maintain the stated 1% accuracy. Check for RoHS compliance documentation if required for regulatory adherence.

Current Sense Transformers Selection Notes

Select this model when a non-contact solution is required for currents up to 80 A. The low 0.333 V output simplifies interface design with ADCs or amplifiers compared to higher current transformers. Consider the split-core form factor for retrofitting existing installations where opening the cable loop is impractical. Validate that the operating frequency range aligns with the system's signal characteristics.

Current Sense Transformers Part Context

This component belongs to the SCT013 series of split-core current sensors. These devices are widely utilized in power management applications requiring galvanic isolation between the high-current primary side and the sensitive secondary measurement electronics. The series offers various ratings to accommodate different current loads while maintaining consistent physical mounting profiles.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the 80 A primary rating and 0.333 V secondary output. Verify identical core geometry for the same conductor clearance. Cross-reference manufacturers offering split-core CTs with comparable frequency response and accuracy specifications.
