VTX-146-300-125

Overview

The Vigortronix VTX-146-300-125 is a 300VA toroidal power transformer designed for open-style PCB or chassis mounting. It features a primary winding rated for 230V AC input. The secondary configuration provides dual windings, each delivering 0-25V AC, resulting in a center-tapped or split-secondary output capability. The unit utilizes 150mm lead lengths for connection. This component complies with UL, CSA, TUV, and EN60950/EN60065 safety standards, ensuring suitability for professional audio and industrial applications requiring robust voltage transformation.

Feature Summary

• Toroidal core construction for efficient magnetic coupling
• Dual secondary windings for flexible voltage configurations
• Compliance with international safety standards including UL and TUV

Applications

• Professional audio equipment power supplies
• Industrial control systems requiring isolated power
• Test and measurement instrumentation

Procurement Notes

Verify the specific voltage rating and lead length requirements against your design schematic before ordering. Confirm that the 230V primary specification matches your local mains supply infrastructure. Ensure the physical dimensions of the open-style toroidal core fit within the designated enclosure space. Check compliance documentation availability if required for final product certification processes.

Selection Notes

Select this model when a 300VA capacity is required with a 230V primary input. The dual 0-25V secondaries are suitable for bridge rectifier circuits or split-rail power supplies. Consider the open style for custom mounting solutions rather than enclosed variants. Evaluate thermal management needs based on the continuous load relative to the 300VA rating.

Part Context

This transformer belongs to the Vigortronix VTX series of toroidal power transformers. The series is characterized by high-quality copper windings and laminated steel cores optimized for low noise and high efficiency. The VTX-146-300-125 variant specifically addresses applications needing precise dual-voltage outputs from a standard single-phase AC source.

Replacement Considerations

Direct substitutes may include other 300VA toroidal transformers with identical 230V primary and dual 0-25V secondary specifications. Verify mechanical footprint and terminal spacing compatibility. Cross-reference safety certifications (UL, CSA, TUV) to ensure equivalent regulatory compliance in the target market.
