VTX-146-015-109

Overview

The Vigortronix VTX-146-015-109 is an open-style toroidal transformer with a power rating of 15VA. It features a single primary winding rated for 230V AC input and dual secondary windings providing 2x 0-9V AC output. The unit has a core size of 28mm x 60mm, weighs 0.3kg, and includes 150mm lead lengths. It exhibits a temperature rise of 26°C and supports a nominal secondary current of 830mA.

Feature Summary

• Open style toroidal construction with flying leads
• Dual secondary windings for split voltage applications
• Compliant with UL, CSA, TUV, EN60950, and EN60065 standards

Applications

• Electronic equipment designs requiring voltage conversion
• Power supply units utilizing split secondary voltages
• Audio or instrumentation circuits needing isolated low-voltage AC sources

Procurement Notes

Verify the specific secondary voltage configuration (0-9V) against circuit requirements to ensure compatibility with downstream rectification or regulation stages. Confirm that the 15VA power rating and 830mA current capacity meet the load demands. Check that the 150mm lead length is sufficient for the intended PCB layout or chassis mounting position without requiring extension cables.

Selection Notes

Select this component when a compact toroidal transformer with dual independent secondary outputs is required for 230V AC mains operation. The open style design facilitates heat dissipation but requires careful mechanical integration to protect the windings. Ensure the application environment complies with the safety standards listed, such as EN60950 for IT equipment or EN60065 for audio/video systems.

Part Context

This model belongs to the Multicomp PRO VTX series of open-style toroidal transformers manufactured by Vigortronix. The series provides various power ratings and voltage configurations for general-purpose power conversion. The VTX-146-015-109 specifically addresses needs for moderate power levels with split-phase secondary requirements in standard industrial or consumer electronics enclosures.

Replacement Considerations

Direct substitutes must match the 15VA rating, 230V primary, and 2x 9V secondary configuration. Verify physical dimensions (28mm x 60mm) and lead length (150mm) for mechanical fit. Ensure equivalent safety certifications are present for the target market.
