VTX-146-225-224

Overview

The Vigortronix VTX-146-225-224 is a 225VA open-style toroidal power transformer with chassis mounting and wire leads. It features dual primary and dual secondary windings, supporting flexible input configurations. The unit provides two 24VAC secondary outputs, delivering a nominal current of 4.68A per winding. Designed for high reliability, it holds UL approval and complies with RoHS standards. The transformer measures 51mm in height and is manufactured in China.

Feature Summary

• Dual primary and dual secondary winding configuration for versatile voltage input and output options
• Open-style toroidal design optimized for efficient magnetic coupling and low electromagnetic interference
• UL approved construction ensuring compliance with international safety standards
• RoHS compliant manufacturing process for environmentally responsible production

Applications

• Industrial control systems requiring isolated power supplies
• Audio equipment power stages needing clean AC voltage
• Medical device instrumentation with strict safety isolation requirements
• Test and measurement apparatus calibration circuits

Procurement Notes

Verify the specific datasheet version to confirm exact physical dimensions and terminal spacing before integration. Ensure the receiving facility handles wire-leaded components carefully to prevent lead damage during storage. Confirm that the dual primary configuration matches the available line voltage at the installation site to avoid operational failure or insulation breakdown.

Selection Notes

Select this model when a robust 225VA capacity is required with precise 24VAC dual outputs. The dual primary design allows compatibility with multiple standard input voltages, simplifying global deployment. Consider the chassis mount style and wire leads for custom enclosure integration where PCB mounting is not feasible. Verify thermal management needs as toroidal transformers generate heat proportional to load.

Part Context

This component belongs to the Vigortronix VTX series of toroidal power transformers, known for high efficiency and compact form factors. The series caters to industrial and commercial applications demanding reliable voltage transformation. The VTX-146-225-224 specifically addresses needs for moderate power levels with dual secondary outputs, fitting into broader system architectures requiring isolated AC sources.

Replacement Considerations

Direct substitutes must match the 225VA rating, 2x24VAC secondary specification, and dual primary configuration. Physical footprint and terminal type (wire leads) must be compatible with existing wiring harnesses. Verify that any replacement also holds UL approval and RoHS compliance to maintain regulatory adherence.
