VTX-146-080-209

Overview

The Vigortronix VTX-146-080-209 is an open-style toroidal transformer with a power rating of 80VA. It features dual primary and dual secondary windings to support flexible voltage configurations. The unit provides a secondary output of 2 x 9V, delivering a nominal secondary current of 4.44A. Designed for PCB installation, this component is UL approved and RoHS compliant, ensuring adherence to safety and environmental standards in electronic equipment applications.

Feature Summary

• Dual primary and dual secondary winding configuration for versatile input/output connections
• Open-style toroidal core design optimized for efficient magnetic coupling
• UL approval and RoHS compliance for regulatory safety and environmental standards

Applications

• Power supply units requiring 18V center-tapped or split-rail outputs
• Audio amplifier circuits utilizing dual 9V secondary windings
• General electronic equipment needing isolated AC voltage transformation

Procurement Notes

Verify the specific pinout and mounting hole dimensions against your PCB layout before ordering. Confirm that the dual primary requirement matches your local mains voltage availability (e.g., series vs. parallel connection for 115V/230V). Ensure the 80VA rating meets the thermal and load requirements of the target application to prevent overheating during continuous operation.

Selection Notes

Select this model when a compact toroidal form factor is required alongside precise 9V secondary outputs. The dual primary design allows compatibility with both 115V and 230V input systems through appropriate wiring. Consider the open style for applications where custom potting or housing integration is planned rather than using pre-encapsulated units.

Part Context

This component belongs to the Vigortronix VTX series of PCB-mounted toroidal transformers. These units are engineered for high efficiency and low noise, making them suitable for sensitive electronic designs. The VTX-146-080-209 specifically addresses needs for moderate power isolation with standardized voltage taps.

Replacement Considerations

Direct substitutes must match the 80VA rating, 2x9V secondary output, and dual primary/dual secondary winding structure. Verify physical footprint compatibility for PCB mounting. Alternative models from other manufacturers should be cross-referenced for identical electrical specifications and UL certification status.
