VTX-146-225-255

Overview

The Vigortronix VTX-146-225-255 is a toroidal transformer with an open style construction and a power rating of 225 VA. It features dual primary windings supporting 115V and 230V input configurations, providing operational flexibility for various mains voltages. The secondary output consists of two independent 55V windings, delivering a total configuration suitable for high-power rectification or balanced supply applications. This component is designed for robust performance in industrial and commercial power systems requiring reliable voltage transformation.

Feature Summary

• Open style toroidal core construction for efficient magnetic coupling
• Dual primary winding design accommodating 115V and 230V inputs
• Dual secondary outputs providing two independent 55V windings

Applications

• Industrial power supply units
• Commercial audio equipment amplifiers
• High-power rectifier circuits

Procurement Notes

Verify the specific pinout configuration and lead length requirements against your chassis design before ordering. Confirm that the dual primary winding setup matches your facility's available line voltage (115V or 230V) to ensure correct installation. Ensure adequate clearance is maintained around the open-style transformer for proper heat dissipation and mechanical mounting stability during operation.

Selection Notes

Select this model when a 225 VA capacity is required with split secondary outputs. The dual primary feature allows adaptation to different regional mains standards without changing hardware. Consider the physical dimensions and weight associated with toroidal designs for structural support needs. Evaluate thermal management strategies given the open construction style which may require specific airflow considerations.

Part Context

This part belongs to the Vigortronix VTX series of toroidal transformers, known for compact size and low leakage flux. The VTX-146-225-255 specifically addresses applications needing higher power handling than standard small signal transformers. Its open style distinguishes it from encapsulated variants, offering easier integration into custom assemblies where space constraints differ.

Replacement Considerations

Direct substitutes must match the 225 VA rating, 2x55V secondary output, and dual primary input capability. Verify that any replacement maintains the same physical footprint and mounting hole pattern. Ensure the new unit supports the same frequency range and insulation class as specified in the original datasheet.
