VTX-146-500-140

Overview

The Vigortronix VTX-146-500-140 is a 500VA toroidal transformer with an open style construction. It features a single 230V AC primary voltage rating. The secondary winding configuration provides dual outputs of 2 x 40V AC at full load, supporting parallel connection for 40V or series connection for 80V. This component is designed for chassis mounting and meets UL safety standards.

Feature Summary

• Toroidal core design for efficient magnetic flux distribution
• Dual secondary windings allowing flexible voltage configuration
• Open style construction facilitating thermal dissipation
• UL approved for compliance with safety regulations

Applications

• Industrial control systems requiring stable power conversion
• Audio equipment power supplies utilizing split rail configurations
• Laboratory test instruments needing precise voltage isolation
• Custom electronic assemblies demanding high reliability

Procurement Notes

Verify the specific secondary voltage requirement matches the application's need for either parallel 40V or series 80V operation. Confirm that the chassis mounting dimensions align with the enclosure design. Ensure the primary voltage rating corresponds to the local mains supply frequency and voltage. Check for any specific UL certification documentation requirements for the final product assembly.

Selection Notes

Select this model when a 500VA capacity is required with a 230V input. Consider the dual secondary options if variable output voltages are needed. Evaluate the open style against environmental protection needs, as it lacks encapsulation. Compare physical dimensions against available space in the target chassis. Assess thermal management capabilities given the exposed coil structure.

Part Context

This part belongs to the Vigortronix VTX-146 series of toroidal transformers. The series offers various power ratings and voltage configurations. The VTX-146-500-140 specifically addresses mid-range power applications. It shares the same form factor and mounting style as other models in the line, differing primarily in electrical specifications.

Replacement Considerations

Direct substitutes include the VTX-146-500-240, which also provides 500VA capacity but may differ in secondary voltage configuration. Verify compatibility by comparing primary voltage, VA rating, and physical footprint. Ensure the replacement maintains the same UL approval status and mounting type.
