SCT019-50-333

Current Sense Transformers Overview

The SCT019-50-333 is a current transformer manufactured by PowerUC Electronics, designed for non-intrusive AC current measurement. It features a split-core design allowing installation without circuit interruption. The device provides an analog voltage output proportional to the primary current, with a rated ratio of 50A to 0.333V and a tolerance of 1%. It operates within a frequency range of 50Hz to 1kHz and supports a maximum primary current of 300A. The unit is classified as a hanging or in-line type transformer suitable for integration into monitoring systems.

Current Sense Transformers Feature Summary

• Split-core construction enables easy installation around existing conductors
• Provides isolated analog voltage output for accurate signal processing
• Supports high overload capacity up to 300A primary current
• Operates effectively across standard power line frequencies up to 1kHz

Current Sense Transformers Applications

• Energy metering and power quality analysis
• Current monitoring in industrial control panels
• Integration with data acquisition systems for load management
• Smart grid infrastructure sensing applications

Current Sense Transformers Procurement Notes

Verify that the required primary conductor diameter fits within the split core aperture before ordering. Confirm that the downstream measurement circuit can accept the 0.333V output signal level at full scale. Ensure the operating environment does not exceed the thermal limits specified in the official datasheet. Check compatibility with the target frequency range if measuring non-standard waveforms.

Current Sense Transformers Selection Notes

Select this model when a low-profile, split-core solution is required for retrofitting existing electrical installations. The 1% accuracy rating makes it suitable for billing-grade or precision monitoring applications. Consider the 50A nominal rating against typical load profiles to ensure optimal resolution. Verify that the 50Hz-1kHz bandwidth aligns with the harmonic content of the measured current.

Current Sense Transformers Part Context

This component belongs to the SCT series of current transformers from PowerUC Electronics. These devices are engineered for reliable current sensing in environments where direct connection is impractical. The series utilizes toroidal core materials optimized for linear response over the specified frequency band. They serve as critical interface elements between high-current circuits and low-voltage measurement electronics.

Current Sense Transformers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. When replacing this unit, ensure the new component matches the 50A/0.333V ratio and 1% tolerance. Verify that the physical dimensions and mounting style are compatible with the existing enclosure or panel layout.
