VTX-146-030-206

Overview

The Vigortronix VTX-146-030-206 is a dual primary toroidal transformer with a 30VA power rating. It accepts 115V or 230VAC input voltage and provides two secondary outputs of 0-6VAC, each capable of delivering 2.5A output current. The unit features typical regulation of 14% and a temperature rise of 40°C. It is UL approved and complies with EN61558, EN60950, C-UL, UKCA, and CE standards. The transformer includes thermal fuses on windings and is supplied with a mounting kit.

Feature Summary

• Dual primary and secondary winding configuration for flexible input and output connections
• Integrated thermal protection via fuses fitted to each winding
• Open style construction designed for integration into custom equipment enclosures

Applications

• Power supply units requiring isolated dual low-voltage AC rails
• Audio amplifier circuits utilizing split-phase power requirements
• Industrial control systems needing compliant isolation transformers

Procurement Notes

Verify that the specific application requires the exact 30VA rating and 0-6VAC dual secondary configuration. Confirm that the open-style form factor fits within the intended mechanical enclosure dimensions. Ensure compliance with local safety regulations such as UL or CE is required for the final assembly. Check that the mounting kit provided meets the installation hardware specifications.

Selection Notes

Select this component when a compact toroidal design is preferred for reduced electromagnetic interference and higher efficiency compared to laminated cores. Choose the dual primary variant if the deployment environment may vary between 115V and 230VAC regions without rewiring. Consider the 30VA limit to ensure the connected load does not exceed the 2.5A per secondary output capacity during peak operation.

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-146-030-206 specifically denotes the 30VA variant with dual 6VAC outputs. It shares the same core geometry and mounting interface characteristics as other models in the VTX-146 family.

Replacement Considerations

Direct substitutes must match the 30VA rating, dual 0-6VAC secondary outputs, and dual primary input capability. Verify that any replacement maintains the same physical footprint and mounting hole pattern. Ensure the substitute also holds relevant safety certifications such as UL or CE if mandated by the end-product requirements.
