Procurement Notes

Verify the specific winding configuration required for your application before ordering. Confirm whether the system requires the secondary windings to be wired in series for 70V or kept separate for 35V outputs. Ensure the mounting hardware provided is compatible with the chassis design. Check input voltage compatibility with the dual primary setup to prevent incorrect wiring.

Selection Notes

Select this model when a 500VA capacity is necessary for applications demanding low noise and high efficiency. The toroidal shape offers a compact footprint relative to laminated transformers. Consider the physical dimensions and weight constraints of the enclosure. Verify that the available space accommodates the open-core design and necessary clearance for heat dissipation.

Part Context

This component belongs to the Vigortronix VTX series of toroidal transformers, known for their use in demanding electronic environments. The series emphasizes durability and consistent performance across various power levels. The VTX-146-500-235 specifically addresses needs for medium-to-high power isolation with flexible voltage options.

Replacement Considerations

When replacing, ensure the new unit matches the 500VA rating and 70V series secondary output. Verify that the primary voltage ratings align with the existing power source. Check that the physical mounting hole pattern and overall dimensions fit the original assembly without modification.
