VTX-146-300-255

Overview

The Vigortronix VTX-146-300-255 is a 300VA open-style toroidal transformer with chassis mounting and wire lead termination. It features dual primary windings for 115V or 230V input and dual secondary outputs of 2 x 55VAC at 2.73A nominal current. The unit measures 125.00mm in diameter and 55.00mm in height. This component is UL approved, RoHS compliant, and designed for high-quality power conversion applications requiring reliable voltage transformation.

Feature Summary

• Dual primary and dual secondary winding configuration for flexible input/output options
• UL approved construction ensuring safety compliance
• RoHS compliant manufacturing standards
• Open style design facilitating chassis integration

Applications

• Industrial control systems requiring isolated power supplies
• Audio equipment power stages needing low noise transformation
• Medical device internal power distribution
• Test and measurement instrument power conditioning

Procurement Notes

Verify the specific voltage rating and physical dimensions against your system requirements before ordering. Confirm that the chassis mount hole pattern matches your enclosure design. Ensure the wire lead length is sufficient for your internal routing needs. Check for any regional certification requirements beyond UL approval. Validate that the 300VA power rating meets the peak load demands of your application to prevent overheating.

Selection Notes

Select this model when a compact toroidal transformer with dual secondary outputs is required. The 125mm diameter fits standard chassis openings. Consider the 55VAC output if your downstream circuitry requires this specific voltage level. The dual primary allows operation in both 115V and 230V regions without rewinding. Ensure adequate ventilation space around the open core for thermal management during continuous operation.

Part Context

This component belongs to the Vigortronix VTX series of toroidal transformers, known for their efficiency and low electromagnetic interference. The VTX-146 series specifically offers various power ratings from 6VA to higher capacities. These transformers are widely used in applications demanding high reliability and stable performance under varying load conditions.

Replacement Considerations

Direct substitutes must match the 300VA rating, 2x55VAC output, and 125mm diameter. Verify that alternative models also feature dual primary/secondary windings and UL approval. Physical mounting compatibility is critical; ensure the new part fits the existing chassis cutout. Check that the wire lead gauge and length are comparable to maintain electrical integrity.
