VTX-146-080-218

Overview

The Vigortronix VTX-146-080-218 is an open-style toroidal power transformer with a rated capacity of 80VA. It features dual primary windings supporting 115V and 230V input configurations, typically connected in parallel for 115V or series for 230V operation. The secondary output provides a center-tapped configuration of 18-0-18VAC. This component is designed for chassis mounting and includes a mounting kit for secure installation.

Feature Summary

• Dual primary winding design enabling flexible voltage compatibility
• Center-tapped secondary output for versatile rectification applications
• Open-style construction with included mounting hardware

Applications

• Audio amplifier power supplies
• Industrial control systems
• Test and measurement equipment

Procurement Notes

Verify the specific pinout and terminal configuration against your circuit schematic before purchase. Confirm that the 80VA rating meets the peak current demands of your load. Ensure the chassis mounting holes align with your enclosure design. Check for any regional voltage requirements regarding the dual primary connections.

Selection Notes

Select this model when an 80VA toroidal transformer with a 36V total secondary voltage is required. Consider the physical dimensions to ensure fit within the available space. Evaluate the thermal performance if the unit will be enclosed. Compare against similar models like the VTX-146-080-212 if a different secondary voltage is needed.

Part Context

This part belongs to the Vigortronix VTX-146 series of toroidal transformers. These units are known for high efficiency and low magnetic interference compared to laminated core types. The series offers various VA ratings and voltage combinations to suit diverse power supply needs.

Replacement Considerations

Direct substitutes include the VTX-146-080-212 (12-0-12V) if voltage differs, or the VTX-146-100-218 (100VA) for higher capacity. Ensure replacement parts match the mounting hole pattern and lead length specifications.
