SCT013-30-333

Current Sense Transformers Overview

The SCT013-30-333 is a split-core current transformer designed for non-invasive AC current measurement. It features a toroidal core with a hinged mechanism, allowing installation around existing conductors without disconnecting the circuit. The device provides an analog voltage output proportional to the primary current, specifically calibrated for a 30 A primary current range. It delivers a standard 0.333 V output signal at full scale, facilitating direct interfacing with data acquisition systems or microcontroller ADCs. The unit operates within a frequency range of 50 Hz to 1 kHz and maintains a measurement accuracy of 1% under specified conditions.

Current Sense Transformers Feature Summary

• Split-core design enables rapid installation on live conductors without power interruption
• Provides isolated electrical measurement for safety in high-current circuits
• Delivers standardized low-voltage analog output suitable for digital sampling

Current Sense Transformers Applications

• Energy monitoring and smart metering systems
• Industrial equipment current surveillance
• Home automation and load management controllers

Current Sense Transformers Procurement Notes

Verify that the required conductor diameter fits within the internal window of the split core before ordering. Confirm that the system input impedance matches the transformer burden requirements to maintain the stated 1% accuracy. Ensure the operating environment does not exceed the thermal limits defined in the official datasheet. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Current Sense Transformers Selection Notes

Select this model when non-intrusive monitoring of alternating currents up to 30 A is required. The 0.333 V output level is optimal for low-voltage logic interfaces. Consider the frequency response limitations if measuring signals outside the 50 Hz to 1 kHz range. This component is suitable for applications where physical access to the conductor is limited or disconnection is impractical.

Current Sense Transformers Part Context

This component belongs to the SCT013 series of split-core current transformers manufactured by PowerUC Electronics. The series offers various current ratings and output configurations to suit different monitoring scales. The SCT013-30-333 variant specifically targets medium-current applications requiring precise analog feedback for control loops or energy calculation algorithms.

Current Sense Transformers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 30 A rating, 0.333 V output, and split-core form factor.
