VTX-146-030-106

Overview

The Vigortronix VTX-146-030-106 is a toroidal power transformer with an open style construction. It features a single primary winding rated for 230V AC input and a secondary configuration providing dual 6V outputs (2 x 6V). The unit has a power rating of 30VA, with a nominal secondary current of 2.5A per winding. Physical dimensions are approximately 35mm in height and 70mm in diameter.

Feature Summary

• Toroidal core design for efficient magnetic flux containment
• Open style construction suitable for custom PCB integration
• Dual secondary windings enabling split-rail or independent power supply architectures

Applications

• Audio amplifier power supplies
• Industrial control systems requiring isolated DC rails
• Test and measurement equipment power stages

Procurement Notes

Verify the specific voltage output configuration against project requirements, as the suffix indicates dual 6V secondary windings. Confirm that the 30VA rating meets the total load demand of the application. Ensure mechanical clearance accommodates the 70mm diameter and 35mm height of the open-style toroidal housing during installation.

Selection Notes

Select this component when a compact, low-noise toroidal transformer is required for 230V AC mains applications. The dual 6V secondary allows for flexible rectification schemes. Consider the open style for direct mounting to chassis or PCBs where shielding is provided externally. Validate thermal management capabilities given the 30VA power dissipation.

Part Context

This model belongs to the Vigortronix VTX-146 series of toroidal transformers. The series offers various power ratings and voltage configurations. The VTX-146-030-106 specifically denotes the 30VA variant with dual 6V secondaries, distinguishing it from other models like the VTX-146-050-225 which offers higher power and different voltage taps.

Replacement Considerations

Direct substitutes must match the 30VA rating, 230V primary, and dual 6V secondary configuration. Verify physical footprint compatibility (35mm x 70mm) and terminal arrangement. Cross-reference with other manufacturers' toroidal transformers offering identical electrical specifications and mounting constraints.
