VTX-146-030-209

Overview

The Vigortronix VTX-146-030-209 is a 30 VA open-style toroidal power transformer designed for PCB mounting. It features dual primary windings rated for 115V and 230V AC input, allowing versatile global application. The secondary configuration provides two independent 9V AC outputs (2 x 9V). Constructed with a ring-shaped magnetic core, this component ensures efficient voltage conversion. It includes thermal fuses for safety and holds UL approval, ensuring compliance with relevant electrical standards for reliable operation in electronic equipment.

Feature Summary

• Dual primary winding design supports both 115V and 230V AC input voltages
• Open style construction facilitates direct PCB installation
• Integrated thermal fuses provide enhanced safety protection
• UL approved for quality and regulatory compliance

Applications

• General purpose electronic equipment power supplies
• Audio amplifier circuits requiring dual low-voltage AC sources
• Industrial control systems needing isolated power stages
• Test and measurement instrumentation power modules

Procurement Notes

Verify the specific voltage rating and winding configuration against your circuit schematic before ordering. Confirm that the open-style form factor fits within the designated enclosure space. Ensure the PCB layout accommodates the lead lengths and mounting requirements specified in the official datasheet. Cross-reference the part number to avoid confusion with similar models having different secondary voltages or VA ratings.

Selection Notes

Select this model when a compact toroidal transformer with dual primary flexibility is required. The 30 VA rating suits moderate power applications. Consider the open style if mechanical mounting constraints allow. Verify that the 2 x 9V secondary output matches the rectification and regulation needs of the downstream circuitry. Check for compatibility with existing thermal management strategies given the enclosed nature of toroidal designs.

Part Context

This component belongs to the Vigortronix VTX series of toroidal transformers, known for high efficiency and low noise. The series offers various VA ratings and winding configurations. The VTX-146-030-209 specifically addresses applications requiring dual primary inputs and split secondary outputs. Toroidal transformers in this category are preferred for their compact size and reduced electromagnetic interference compared to laminated core alternatives.

Replacement Considerations

Direct substitutes must match the 30 VA rating, dual primary (115/230V) input, and 2 x 9V secondary output. Verify physical dimensions and lead configurations for PCB compatibility. Ensure equivalent safety certifications (UL, CSA, TUV) are present. Consult manufacturer cross-reference tools for parametrically similar parts, but validate all electrical parameters independently.
