VTX-146-500-255

Overview

The Vigortronix VTX-146-500-255 is a 500 VA toroidal transformer designed for chassis mounting. It features dual primary windings supporting 115V and 230V input voltages. The secondary configuration provides parallel 55V or series 110V outputs at a maximum current of 4.55A. This open-style component utilizes wire leads for connection and operates without hazardous substances.

Feature Summary

• Toroidal core construction for efficient magnetic coupling
• Dual primary winding capability for global voltage compatibility
• Flexible secondary output options via parallel or series connection
• Chassis mount design with wire lead terminals

Applications

• Power supply units requiring isolated AC voltage transformation
• Audio equipment power stages needing low noise operation
• Industrial control systems utilizing chassis-mounted transformers
• Test and measurement instrumentation power circuits

Procurement Notes

Verify the specific secondary voltage requirement (55V parallel vs 110V series) against the application circuit before ordering. Confirm that the chassis mounting dimensions and wire lead lengths meet the enclosure constraints. Ensure the input voltage matches the available primary supply (115V or 230V). Check for any specific environmental ratings if the operating location exceeds standard conditions.

Selection Notes

Select this model when a high-efficiency, low-noise toroidal transformer is required for 500 VA applications. The dual primary winding allows flexibility for different regional mains voltages. Consider the physical size and weight compared to laminated alternatives. Ensure the wire lead termination method suits the assembly process. Verify thermal management requirements for continuous full-load operation.

Part Context

This component belongs to the Vigortronix VTX series of PCB and chassis-mount transformers. The series offers various power ratings and configurations. The VTX-146-500-255 specifically addresses higher power needs with its 500 VA rating. Toroidal designs in this line are chosen for their compact form factor and reduced electromagnetic interference compared to traditional E-I core transformers.

Replacement Considerations

Direct replacements must match the 500 VA rating, 50/60 Hz frequency, and identical electrical specifications. Physical footprint and mounting hole patterns must align for chassis installation. Secondary voltage and current capabilities must be equal or exceed original requirements. Verify terminal type compatibility if direct wire replacement is not feasible.
