VTX-146-080-225

Overview

The Vigortronix VTX-146-080-225 is an open-style toroidal transformer with a power rating of 80VA. It features dual primary windings for 115V and 230V operation, providing versatile mains compatibility. The secondary configuration offers two isolated 25V outputs, supporting a nominal current of 1.6A per winding. Designed for chassis mounting, the unit includes a dedicated mounting kit for secure installation. Each component undergoes 100% electrical and flash testing to ensure reliability and performance standards in power supply applications.

Feature Summary

• Open-style toroidal core design for efficient magnetic coupling
• Dual primary windings enabling flexible 115V or 230V input selection
• Dual secondary windings providing isolated output channels
• Integrated internal thermal fuse for enhanced safety protection

Applications

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

Procurement Notes

Verify that the specific part number matches the required voltage and current specifications for your application. Confirm that the chassis mounting style and wire lead terminals are compatible with your enclosure design. Ensure that the dual primary voltage requirements align with your local mains supply standards before procurement.

Selection Notes

Select this model when an 80VA capacity with dual 25V secondary outputs is required. The dual primary feature allows adaptation to different regional voltage standards without changing hardware. Consider the open-style construction and chassis mounting requirements during the mechanical design phase to ensure proper fit and ventilation.

Part Context

This component belongs to the Vigortronix VTX series of PCB and chassis-mounted transformers. These units are engineered for general-purpose power conversion tasks. The VTX-146-080-225 specifically addresses applications needing moderate power isolation with dual secondary outputs, fitting within the broader category of toroidal power transformers used in electronic equipment.

Replacement Considerations

The VTX-146-080-224 serves as a direct substitute if a 24V secondary output is acceptable instead of 25V. Both models share identical 80VA ratings, dual primary configurations, and physical mounting characteristics. Verify that the slight voltage difference does not impact downstream circuit requirements before swapping components.
