VTX-146-120-218

Overview

The Vigortronix VTX-146-120-218 is a dual primary toroidal transformer with a power rating of 120 VA. It features an open style construction and provides a dual secondary winding configuration delivering 0-18V AC at 0-18V AC. The unit is UL approved and complies with EN61558, EN60950, C-UL, UKCA, and CE standards. It is supplied with a mounting kit for installation.

Feature Summary

• Dual primary winding design for flexible input voltage compatibility
• Open style toroidal core construction for efficient magnetic coupling
• Comprehensive regulatory compliance including UL, CE, and UKCA approvals

Applications

• Power supply units requiring isolated dual voltage rails
• Audio equipment amplifiers utilizing split power supplies
• Industrial control systems needing reliable AC voltage transformation

Procurement Notes

Verify the specific voltage requirements match the 0-18V 0-18V output specification. Confirm that the dual primary winding configuration aligns with your available input power source. Ensure physical dimensions accommodate the open style form factor and that the included mounting kit meets your chassis requirements. Check for updated compliance certifications if operating in regulated markets.

Selection Notes

Select this component when a 120 VA capacity is required with symmetrical dual secondary outputs. The dual primary feature allows adaptation to different regional line voltages without rewinding. Consider the open style design for applications where thermal dissipation from the core surface is beneficial or where custom encapsulation is planned later.

Part Context

This model belongs to the Vigortronix VTX-146 series of toroidal transformers. The series offers various power ratings and voltage configurations. The VTX-146-120-218 specifically denotes the 120 VA rating and the 2x18V output configuration within this standardized product line designed for general purpose power conversion.

Replacement Considerations

Direct substitutes must match the 120 VA rating, 0-18V 0-18V output, and dual primary winding structure. Verify physical footprint compatibility as toroidal transformers vary significantly in diameter and height across manufacturers. Ensure equivalent insulation class and temperature rise characteristics are maintained for safety compliance.
