VTX-151-1563

Overview

The Vigortronix VTX-151-1563 is a PCB precision current sensing transformer designed for through-hole mounting. It features a turns ratio of 1:2000 and supports a maximum primary current of 20 A. The device operates within a frequency range of 20 Hz to 20 kHz and includes an internal burden resistance of 100 ohms. Accuracy specifications range from 0.2% to 1%. The component is epoxy encapsulated with a built-in busbar, ensuring mechanical stability and electrical isolation for reliable current monitoring applications.

Feature Summary

• Precision current sensing with integrated busbar design
• Wide operational frequency range suitable for diverse signal spectra
• High accuracy performance for precise measurement requirements

Applications

• AC/DC current monitoring in power distribution systems
• Overcurrent protection circuitry
• Power quality analysis equipment

Procurement Notes

Verify the specific accuracy grade required for your application, as the datasheet indicates a range of 0.2% to 1%. Confirm that the 20 A maximum current rating aligns with peak load conditions. Ensure the 100 ohm internal burden matches your downstream ADC or amplifier input impedance. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a wide bandwidth up to 20 kHz is necessary, distinguishing it from standard 50/60 Hz only transformers. The 1:2000 ratio provides significant signal attenuation, requiring appropriate amplification stages. Consider the physical dimensions and through-hole mounting style for PCB layout compatibility. This model is distinct from similar Vigortronix parts like the VTX-151-1567 which targets lower frequencies.

Part Context

This part belongs to Vigortronix's line of precision current sense transformers. Unlike general-purpose current transformers, this model emphasizes high accuracy and broad frequency response. It serves as a critical interface between high-current lines and low-voltage measurement circuits, providing galvanic isolation while maintaining signal integrity across its specified operational range.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Similar models such as the VTX-151-1567 differ significantly in frequency range (50/60 Hz vs 20Hz-20kHz) and may not be interchangeable. Verify pinout, ratio, and frequency specs before considering any alternative components.
