VTX-146-160-255

Overview

The Vigortronix VTX-146-160-255 is an open-style toroidal power transformer with a maximum power rating of 160VA. It features dual primary windings supporting 115V and 230V input voltages, and dual secondary windings providing two outputs of 55V each. The unit utilizes wire lead termination for connection and is designed for chassis mounting. Physical dimensions include a diameter of 105.00mm and a maximum seated height of 47.00mm.

Feature Summary

• Toroidal core construction for efficient magnetic flux linkage
• Dual primary winding configuration for versatile voltage compatibility
• Dual secondary winding design enabling multiple output requirements
• Open style architecture facilitating custom integration

Applications

• Chassis-mounted audio amplifier power supplies
• Industrial control systems requiring isolated power
• Test and measurement equipment power stages

Procurement Notes

Verify that the specific application requires the dual 55V secondary configuration and 160VA capacity. Confirm that chassis mounting provisions are available in the target enclosure. Ensure input voltage selection matches the dual primary winding specifications. Check that wire lead termination aligns with the system's wiring harness or terminal block design before finalizing procurement.

Selection Notes

Select this component when high-power isolation and dual voltage inputs are necessary. The toroidal shape offers superior efficiency compared to laminated cores. Consider the physical footprint constraints due to the 105mm diameter. Verify thermal management requirements as open-style transformers dissipate heat directly into the surrounding environment without enclosed housing.

Part Context

This model belongs to the Vigortronix VTX series of toroidal power transformers. These components are engineered for robust performance in demanding electronic applications. The series emphasizes reliability through rigorous electrical and flash testing during manufacturing. They serve as critical interface elements between AC mains and sensitive DC or low-voltage AC loads.

Replacement Considerations

Direct substitutes must match the 160VA rating, 115/230V dual primary, and 2x55V dual secondary configuration. Compatible replacements should maintain similar physical dimensions for chassis fitment. Verify insulation class and temperature rise characteristics against original specifications.
