VTX-146-225-230

Overview

The Vigortronix VTX-146-225-230 is a dual primary toroidal transformer with a 225VA power rating. It supports 115V and 230VAC input voltages via its dual primary windings. The secondary configuration provides two outputs of 30VAC each, delivering a maximum current of 3.75A per winding. Typical voltage regulation is 7%, with a temperature rise of 60°C under load. The unit features an open style design for chassis mounting and has a height of 51mm. This component is UL approved.

Feature Summary

• Dual primary winding configuration enables compatibility with both 115V and 230VAC input systems.
• Open style construction facilitates direct chassis mounting in electronic enclosures.
• UL approval ensures compliance with specific safety standards for electrical components.

Applications

• Power supply units requiring dual secondary outputs
• Audio equipment amplifiers
• Industrial control systems

Procurement Notes

Verify the specific datasheet version to confirm regulatory approvals and mechanical dimensions. Ensure the application circuit matches the dual primary wiring requirements for the target input voltage. Confirm that the chassis mounting space accommodates the 51mm height and overall footprint. Cross-reference the secondary current ratings with the actual load requirements to prevent overheating.

Selection Notes

Select this model when a 225VA capacity is required with split secondary voltages. The dual primary feature is essential for global input voltage flexibility without manual rewiring. Consider the open style design if thermal management allows for direct air exposure. Verify that the 30VAC output aligns with downstream rectification or regulation needs.

Part Context

This component belongs to the Vigortronix VTX series of toroidal transformers. These transformers are characterized by their low magnetic leakage and compact form factor compared to laminated cores. The VTX-146-225-230 specifically addresses applications needing isolated dual outputs from a single core structure.

Replacement Considerations

Direct substitutes must match the 225VA rating, 2x30VAC secondary output, and dual primary input capability. Mechanical compatibility requires similar mounting hole patterns and height constraints. Verify that any replacement maintains equivalent regulation and temperature rise characteristics.
