VTX-146-030-224

Overview

The Vigortronix VTX-146-030-224 is a 30VA toroidal power transformer designed for PCB installation. It features dual primary windings supporting 115V and 230V inputs, and dual secondary windings configurable for parallel 24V or series 48V outputs at a maximum current of 625mA. The unit includes thermal fuses for protection and utilizes an open style construction.

Feature Summary

• Dual primary and secondary winding configurations for flexible voltage input and output options
• Integrated thermal fuse protection to enhance operational safety
• Open style design suitable for direct PCB mounting in electronic equipment

Applications

• General purpose power supply units requiring isolated AC voltage conversion
• Audio equipment power stages needing low noise toroidal transformers
• Industrial control systems utilizing standard 115V/230V mains inputs

Procurement Notes

Verify the specific voltage configuration required for your application, as this model supports both parallel 24V and series 48V secondary outputs. Confirm that the 30VA rating and 625mA current capacity meet the load requirements. Ensure the PCB layout accommodates the physical dimensions of the open-style toroidal core and provides adequate clearance for the thermal fuse components.

Selection Notes

Select this component when a compact, high-efficiency toroidal solution is needed for 30VA applications. The dual winding capability allows adaptation to different regional mains voltages and output requirements without changing the core part number. Consider the open style for cost-sensitive designs where shielding is not critical, and verify that the thermal protection aligns with safety standards for the target market.

Part Context

This transformer belongs to the Vigortronix VTX series of PCB-mounted toroidal transformers. These components are engineered for reliability in consumer and industrial electronics. The VTX-146-030-224 specifically addresses the need for versatile voltage transformation in a small footprint, leveraging toroidal geometry for improved magnetic efficiency compared to laminated cores.

Replacement Considerations

Direct substitutes must match the 30VA rating, toroidal form factor, and dual winding electrical characteristics. Verify that any replacement offers compatible thermal fuse specifications and similar physical mounting dimensions to ensure PCB compatibility without mechanical modification.
