VTX-146-080-215

Overview

The Vigortronix VTX-146-080-215 is an open-style toroidal transformer with a power rating of 80VA. It features dual primary windings for 115V and 230V operation, providing versatile input compatibility. The secondary output is configured as 0-15V, delivering two separate 15V outputs (2x15V) suitable for full-wave rectification circuits. This component utilizes thermal fuses fitted to each winding for enhanced safety protection against overheating.

Feature Summary

• Dual primary winding configuration supports both 115V and 230V AC input voltages.
• Integrated thermal fuses are fitted to each winding for internal safety protection.
• Open-style construction allows for flexible integration into custom chassis or enclosures.

Applications

• Audio amplifier power supplies
• Linear regulated DC power supply units
• Industrial control equipment requiring isolated AC sources

Procurement Notes

Verify the specific voltage configuration required for your design, as this unit provides dual 15V secondaries. Confirm that the open-frame mechanical dimensions fit within your assembly constraints. Ensure the thermal fuse ratings align with your system's safety standards. Cross-reference the part number suffix to confirm the exact tap configuration matches your schematic requirements before finalizing orders.

Selection Notes

Select this model when a compact, high-efficiency toroidal core is needed for 80VA applications. The dual primary feature simplifies global deployment without changing hardware. Consider the physical size and weight compared to laminated transformers if space is limited. Verify that the 0-15V center-tapped output matches your rectifier topology needs.

Part Context

This component belongs to the Vigortronix VTX series of PCB and chassis-mount toroidal transformers. These units are designed for general-purpose power conversion in electronic equipment. The series emphasizes high efficiency and low magnetic interference due to the toroidal core geometry, making them suitable for sensitive analog circuits.

Replacement Considerations

Direct substitutes must match the 80VA rating, 2x15V secondary output, and dual primary input capability. Check mechanical mounting hole patterns and overall diameter/height for compatibility. Ensure equivalent thermal protection mechanisms are present in alternative models to maintain safety compliance.
