Overview
The Vigortronix VTX-146-050-106 is a toroidal power transformer featuring a single primary winding rated for 230V AC input. It provides dual secondary outputs of 2 x 6V, delivering a total power capacity of 50VA. The unit utilizes an SS-146 core and measures approximately 34mm in height by 81mm in diameter. Designed for PCB mounting, this open-frame component ensures efficient voltage conversion for electronic applications requiring stable low-voltage DC supply after rectification.
Feature Summary
- Toroidal core construction for enhanced magnetic efficiency
- Dual secondary windings for split-rail or independent circuits
- PCB mounting design for direct board integration
Applications
- Audio amplifier power supplies
- Electronic test equipment
- Industrial control systems
Procurement Notes
Verify the specific pinout configuration against your PCB footprint before ordering. Confirm that the 230V primary rating matches your local mains voltage standards. Ensure the 50VA power budget accommodates the peak current requirements of your downstream circuitry to prevent saturation.
Selection Notes
Select this model when a compact toroidal solution with dual 6V outputs is required. Compare physical dimensions (34mm x 81mm) against available board space. Consider thermal management needs as open-frame transformers may require adequate airflow for continuous operation at full load.
Part Context
This component belongs to the Vigortronix VTX series of PCB-mounted toroidal transformers. These units are characterized by their high efficiency and low electromagnetic interference compared to traditional laminated cores. The SS-146 core designation indicates a specific steel grade optimized for power distribution tasks.
Replacement Considerations
Direct substitutes must match the 50VA rating, 230V primary, and 2x6V secondary specifications. Verify that alternative models maintain identical mounting hole patterns and terminal configurations to ensure mechanical compatibility without redesigning the PCB layout.
