VTX-146-500-225

Overview

The Vigortronix VTX-146-500-225 is a 500VA toroidal transformer designed for chassis mounting. It features dual primary windings supporting 115V and 230V input voltages. The secondary configuration provides two 25V outputs, allowing for parallel operation at 25V or series operation at 50V. With a maximum output current of 10A, this open-style unit utilizes wire leads for connection. It complies with RoHS standards and contains no SVHC substances as of January 2025.

Feature Summary

• Toroidal core construction for efficient magnetic flux containment
• Dual primary winding capability for versatile voltage input
• Flexible secondary output options via parallel or series connection
• Chassis mount design with wire lead terminals

Applications

• Data acquisition systems
• Data logging equipment
• Oscilloscopes
• Tool accessories power supplies

Procurement Notes

Verify the specific secondary voltage requirement (25V parallel vs 50V series) against the target circuit design before ordering. Confirm that the chassis mounting style and wire lead termination are compatible with the assembly process. Ensure the 500VA power rating meets the peak load demands of the application to prevent thermal overload during continuous operation.

Selection Notes

Select this model when a high-efficiency toroidal transformer is required for industrial instrumentation. The dual primary winding allows compatibility with both 115V and 230V mains without manual rewiring. The open style facilitates custom cooling solutions, while the chassis mount ensures mechanical stability in heavy-duty environments requiring reliable voltage transformation.

Part Context

This component belongs to the Vigortronix VTX series of toroidal transformers. These units are engineered for robust performance in electronic equipment where size efficiency and low electromagnetic interference are critical. The VTX-146-500-225 specifically addresses applications needing substantial power handling with flexible output configurations.

Replacement Considerations

Direct substitutes must match the 500VA rating, toroidal form factor, and dual 25V secondary configuration. Verify physical dimensions for chassis mounting compatibility. Ensure the replacement part supports the same dual primary voltage inputs and maintains RoHS compliance for regulatory adherence.
