VTX-146-050-206

Overview

The Vigortronix VTX-146-050-206 is a 50VA open-style toroidal power transformer featuring dual primary and secondary windings. It accepts 115V or 230V AC input via parallel primary connections. The secondary output provides two 6V windings, configurable for series connection to yield 12V at 4.17A or parallel operation. Constructed with twin windings under strict quality control, it includes thermal fuses on each primary winding for enhanced safety. The unit measures approximately 82mm in diameter and 33-35mm in height, utilizing wire leads for termination.

Feature Summary

• Dual primary and secondary winding configuration for flexible voltage selection
• Integrated thermal fuses fitted to each primary winding for protection
• UL approved high-quality open style toroidal design
• Wire leaded terminals for direct connection

Applications

• Audio equipment power supplies
• General purpose low voltage AC power conversion
• Industrial control systems requiring isolated power
• Test and measurement instrumentation

Procurement Notes

Verify the specific secondary configuration required (series vs parallel) against the application circuit before ordering. Confirm that the wire lead length and gauge meet the installation requirements. Ensure the input voltage matches the available supply (115V/230V) and that the primary windings are connected in parallel as specified for this model. Check for any regional certification requirements beyond UL approval if applicable.

Selection Notes

Select this component when a compact toroidal transformer with dual independent secondary outputs is needed. The 50VA rating suits moderate load applications. Consider the physical dimensions (82mm x 33mm) for enclosure space constraints. The open style requires careful mounting to avoid short circuits. Verify that the 4.17A current capacity meets the maximum load demand in the chosen secondary configuration.

Part Context

This part belongs to the Vigortronix VTX series of open-style toroidal transformers. These components are designed for general power transformation tasks where size efficiency and electrical isolation are priorities. The series typically offers various VA ratings and voltage combinations, with this specific model focusing on dual 6V outputs derived from a 50VA core.

Replacement Considerations

Direct substitutes must match the 50VA power rating, dual 6V secondary configuration, and toroidal form factor. Verify compatibility of primary voltage inputs and terminal types. Cross-reference with other manufacturers' toroidal transformers offering identical electrical specifications and physical footprint constraints.
