VTX-146-500-155

Overview

The Vigortronix VTX-146-500-155 is a 500VA toroidal power transformer designed for chassis mounting. It features a single 230V AC primary winding and dual secondary windings providing 0-55V AC at 4.55A each, configured for parallel operation. The unit utilizes an open style construction with 150mm lead lengths for connection. This component complies with UL, CSA, TUV, EN60950, and EN60065 safety standards, ensuring reliable performance in industrial and commercial applications requiring stable voltage transformation.

Feature Summary

• Toroidal core design for efficient magnetic flux containment
• Dual independent secondary windings for flexible output configuration
• Open frame construction facilitating direct chassis integration
• Compliance with major international safety certification standards

Applications

• Industrial control systems requiring isolated power supplies
• Commercial audio equipment power stages
• Test and measurement instrumentation power units
• Medical device internal power distribution

Procurement Notes

Verify the specific secondary voltage rating (0-55V) and current capacity (4.55A) against your circuit requirements before ordering. Confirm that the chassis mounting holes align with your enclosure design. Ensure the input voltage matches the 230V primary specification. Check for required safety certifications (UL/CSA/TUV) relevant to your target market regulations. Validate lead length compatibility with your wiring layout.

Selection Notes

Select this model when a 500VA capacity is necessary for high-current applications. Choose the dual 55V secondary configuration if balanced split-rail or parallel high-current outputs are needed. Consider the open style form factor if space constraints allow for external mounting rather than enclosed housing. Verify that the 230V primary input matches your local mains supply or available transformer tap settings.

Part Context

This component belongs to the Vigortronix VTX series of PCB and chassis mount transformers. The VTX-146-500-155 specifically denotes the 500VA power rating and the 155 suffix indicating the 0-55V secondary configuration. It is part of a broader family of toroidal transformers offering various voltages and wattages for diverse electronic power needs.

Replacement Considerations

Direct substitutes may include other 500VA toroidal transformers with identical 230V primary and dual 55V secondary specifications. Verify physical dimensions and mounting hole patterns to ensure mechanical compatibility. Cross-reference electrical parameters such as regulation and efficiency if replacing with a different manufacturer's equivalent.

FAQ

Can the secondary windings be connected in series?

Yes, the dual 0-55V windings can typically be connected in series to provide a higher voltage output, though parallel connection is standard for increased current capacity.

What is the maximum current per secondary winding?

Each secondary winding is rated for 4.55A at 55V.
