VTX-146-500-224

Overview

The Vigortronix VTX-146-500-224 is a 500 VA toroidal transformer featuring an open style construction. It supports dual primary voltages of 115V and 230V, providing flexibility for various input power standards. The unit utilizes a dual secondary configuration delivering two isolated 24V outputs. Designed for wire leaded connections, this component ensures efficient voltage transformation in high-power electronic applications requiring robust thermal management and low electromagnetic interference.

Feature Summary

• Open style toroidal core design for enhanced thermal dissipation
• Dual primary winding capability supporting 115V and 230V inputs
• Dual secondary windings providing isolated 24V outputs
• Wire leaded termination method for direct circuit integration

Applications

• High-power audio amplifier systems
• Industrial control equipment power supplies
• Test and measurement instrument power stages
• Medical device internal power distribution

Procurement Notes

Verify the specific pinout configuration and wire gauge requirements against your PCB layout or terminal block specifications before integration. Confirm that the physical dimensions of the open-style toroid fit within the designated enclosure space, accounting for necessary clearance for heat dissipation. Ensure the input voltage selection matches the local mains supply to prevent operational failure.

Selection Notes

Select this model when a 500 VA capacity is required with dual 24V secondary outputs. The dual primary feature allows compatibility with both North American and international power standards without external switching components. Consider the open style for applications where mounting hardware can be integrated directly into the chassis structure rather than using enclosed cases.

Part Context

This component belongs to the Vigortronix VTX series of toroidal transformers, which are characterized by their circular core geometry and high efficiency. The series offers various power ratings and voltage configurations to suit different industrial and commercial power supply needs. The VTX-146-500-224 specifically addresses the need for higher power handling in compact forms.

Replacement Considerations

Cross-reference tools may identify parametrically similar parts from other manufacturers. Verify that any substitute maintains the exact 500 VA rating, dual 24V secondary configuration, and dual primary input support. Physical footprint and wire lead length must also match to ensure mechanical compatibility.
