VTX-151-1564

Overview

The Vigortronix VTX-151-1564 is a precision current sensing transformer designed for through-hole PCB mounting. It features a turns ratio of 1:2000 and supports a primary current rating of 20 A. The operational frequency range spans from 20 Hz to 20 kHz, with an internal burden resistance of 100 ohms. This component integrates a built-in busbar structure to facilitate direct conductor insertion. Accuracy specifications are documented within the range of 0.2% to 1%, ensuring reliable signal fidelity for high-current monitoring applications in electronic equipment designs.

Feature Summary

• Precision current sensing capability with integrated busbar design
• Wide operational frequency range supporting low to mid-frequency signals
• Through-hole mounting configuration for secure PCB installation

Applications

• High-current monitoring in power distribution systems
• Electronic equipment stability and efficiency verification
• Current feedback loops in voltage regulation circuits

Procurement Notes

Verify the specific accuracy class required for your application, as documentation indicates a range of 0.2% to 1%. Confirm that the 20 Hz lower frequency limit aligns with your system's operational spectrum. Ensure the 20 A primary current rating exceeds peak loads to prevent saturation. Cross-reference the 100 ohm internal burden with your downstream circuit impedance requirements before finalizing procurement.

Selection Notes

Select this component when precise current measurement is critical for system stability. The 1:2000 ratio provides significant signal attenuation suitable for sensitive detection circuits. Consider the 20 Hz minimum frequency constraint; it is unsuitable for DC or near-DC applications. The built-in busbar simplifies assembly compared to separate core-and-winding solutions. Evaluate thermal performance under continuous 20 A load conditions.

Part Context

This part belongs to the Vigortronix VTX series of PCB-mounted current transformers. These components are engineered for integration into electronic devices where voltage regulation and power distribution require accurate current feedback. The series emphasizes reliability and efficiency in industrial and commercial power management contexts.

Replacement Considerations

Publicly confirmed substitute part numbers include VTX-151-1563 and VTX-151-1567. Verify compatibility regarding current ratings and frequency ranges, as VTX-151-1567 specifies different nominal current limits and frequency characteristics.
