Procurement Notes

Verify the specific pinout and physical dimensions against your PCB layout before ordering. Confirm that the dual primary requirement matches your available input voltage source. Ensure the open style form factor fits within the designated enclosure space without obstruction. Check for any additional mechanical mounting requirements specified in the official datasheet.

Selection Notes

Select this model when a 500 VA capacity is required with a 90V center-tapped secondary output. The dual primary feature allows operation across different line voltages if wired appropriately. Consider the open style design for applications where thermal dissipation from the core surface is beneficial. Ensure the PCB footprint accommodates the terminal spacing and height constraints.

Part Context

This component belongs to the Vigortronix VTX series of toroidal transformers, which are known for their compact size and low magnetic interference. The VTX-146-500-245 specifically addresses mid-power applications needing reliable isolation and voltage transformation. It is part of a broader range offering various VA ratings and voltage configurations for diverse industrial and commercial uses.

Replacement Considerations

Direct substitutes must match the 500 VA rating, 2x45V secondary, and dual primary configuration. Verify that alternative models maintain the same open style and UL certification. Physical dimensions and terminal pitch must be compatible with existing PCB layouts. Consult manufacturer cross-reference lists for verified equivalent part numbers.
