VTX-146-500-230

Overview

The Vigortronix VTX-146-500-230 is a 500 VA open-style toroidal transformer featuring dual primary windings for 115V or 230V AC input. It provides two secondary windings delivering 0-30V AC, offering flexible voltage options. The unit includes 150mm lead lengths for connection. It is UL approved and complies with CSA, TUV, EN60950, and EN60065 standards. The transformer undergoes 100% electrical and flash testing to ensure reliability.

Feature Summary

• Dual primary winding configuration supports both 115V and 230V AC input voltages
• Open style construction facilitates direct mounting and integration into custom enclosures
• Dual secondary windings provide independent 0-30V AC outputs for versatile power distribution
• Comprehensive safety compliance including UL approval and international standard certifications

Applications

• Audio amplifier power supplies
• Industrial control equipment
• Test and measurement instruments
• Custom electronic device power systems

Procurement Notes

Verify that the required input voltage matches the dual primary specification of 115V or 230V AC. Confirm that the load requirements do not exceed the 500 VA rating across the combined secondary outputs. Ensure the enclosure design accommodates the open-style form factor and allows for adequate ventilation. Check that the 150mm lead length is sufficient for the intended wiring layout without requiring extension cables.

Selection Notes

Select this model when a compact, high-efficiency toroidal solution is needed for dual-voltage applications. The dual secondary windings allow for series or parallel connections to achieve different voltage levels. Consider the open style if space constraints prevent the use of enclosed transformers. Verify that the target application requires AC output rather than rectified DC, as this component does not include rectification circuitry.

Part Context

This component belongs to the Vigortronix VTX-146 series of toroidal transformers. The series offers various power ratings and voltage configurations. The VTX-146-500-230 specifically denotes the 500 VA capacity and 230V primary variant within this lineup. It is designed for general-purpose power transformation in electronics where size and weight efficiency are critical.

Replacement Considerations

Direct substitutes must match the 500 VA rating, dual 0-30V secondary configuration, and dual primary input capability. Verify physical dimensions and lead length compatibility. Ensure replacement units maintain equivalent safety certifications such as UL and TUV. Generic toroidal transformers may lack the specific dual secondary winding arrangement required for this application.
