VTX-146-625-140

Overview

The Vigortronix VTX-146-625-140 is a 625VA toroidal power transformer designed for chassis mounting. It features a single primary winding rated for 230V AC input and dual secondary windings providing 2 x 40V at 8.8A. The unit incorporates an internal thermal fuse for overtemperature protection, ensuring operational safety under fault conditions. Constructed with high-quality laminated steel cores and copper windings, it delivers stable voltage regulation suitable for demanding industrial applications.

Feature Summary

• Toroidal core geometry for compact footprint and reduced electromagnetic interference
• Dual secondary windings enabling flexible series or parallel output configurations
• Integrated thermal fuse mechanism for automatic shutdown during overheating events

Applications

• Industrial control systems requiring robust power isolation
• Audio amplifier equipment needing low-noise power supplies
• Medical instrumentation demanding high reliability and safety compliance

Procurement Notes

Verify the specific secondary current rating of 8.8A against your load requirements to ensure adequate capacity. Confirm that the chassis mounting holes align with your enclosure design specifications. Check for regional safety certifications such as UL or CE if required for your market. Ensure the 230V primary voltage matches your local supply infrastructure before installation.

Selection Notes

Select this model when high power density and low magnetic leakage are critical. The toroidal shape offers superior efficiency compared to traditional E-I transformers. Consider the physical dimensions and weight for mechanical support needs. Evaluate the need for dual outputs versus a single higher-voltage alternative based on circuit topology.

Part Context

This component belongs to the Vigortronix VTX 146 series, which specializes in high-performance toroidal transformers. The series is engineered for applications requiring strict adherence to safety standards like EN61558. These units are characterized by their durable construction and consistent performance across varying environmental conditions.

Replacement Considerations

Direct substitutes must match the 625VA rating, 230V primary, and 2x40V secondary configuration. Verify that any replacement maintains the same physical mounting dimensions and terminal layout. Ensure equivalent thermal protection mechanisms are present to preserve system safety integrity.
