VTX-146-500-135

Overview

The Vigortronix VTX-146-500-135 is a 500VA toroidal power transformer designed for mains applications. It features an open-style construction with a circular magnetic core. The unit includes a 230V AC primary winding and dual secondary windings providing 0-35V AC output. Each secondary winding has a current rating of 7.1A, resulting in a total apparent power capacity of 500VA. The device incorporates an internal thermal fuse for safety protection and utilizes 150mm lead lengths for connection.

Feature Summary

• Open-style toroidal design with circular magnetic core
• Internal thermal fuse for overload protection
• Dual secondary windings for flexible voltage configuration
• Compliant with UL, CSA, TUV, EN60950, and EN60065 standards

Applications

• Audio equipment power supplies
• Industrial control systems
• Medical instrumentation
• Test and measurement devices

Procurement Notes

Verify the specific secondary voltage configuration (0-35V) matches the target circuit requirements before procurement. Confirm that the 150mm lead length is sufficient for the intended PCB or chassis mounting layout. Ensure the ambient operating temperature does not exceed the thermal fuse limits. Check for required certifications such as UL or TUV depending on regional compliance needs. Validate input voltage compatibility with the 230V primary specification.

Selection Notes

Select this model when a high-efficiency toroidal transformer with 500VA capacity is required. Consider the open style if housing integration allows for direct airflow cooling. Choose based on the need for dual 35V outputs rather than single higher voltage options. Evaluate space constraints against the physical dimensions typical of 500VA toroidal cores. Ensure the application benefits from the low electromagnetic interference characteristic of toroidal designs.

Part Context

This component belongs to the Vigortronix VTX series of toroidal transformers. These units are characterized by their ring-shaped core geometry which minimizes magnetic flux leakage. The series offers various VA ratings and voltage configurations. This specific part number denotes the 500VA variant with defined secondary outputs. It is positioned as a robust solution for mains-powered electronic equipment requiring stable voltage transformation.

Replacement Considerations

Direct substitutes must match the 500VA rating, 230V primary, and dual 0-35V secondary configuration. Verify that replacement units maintain the same lead length and thermal protection mechanisms. Cross-reference physical dimensions to ensure fit within existing enclosures. Confirm that alternative parts hold equivalent safety certifications for the target market.
