Overview
The Vigortronix VTX-146-225-118 is a toroidal power transformer with a 225 VA rating. It features a single primary winding designed for 230V AC input and dual secondary windings providing 2 x 18V AC output. The unit utilizes lead wire terminals for connection and is constructed for chassis mounting applications. Its physical dimensions are specified as 50mm in diameter by 110mm in height.
Feature Summary
- Toroidal core construction for efficient magnetic flux containment
- Dual secondary windings enabling split voltage configurations
- Lead wire termination style for flexible integration
Applications
- Chassis-mounted industrial power supplies
- Audio equipment power stages requiring isolated outputs
- General purpose AC to AC voltage transformation in enclosures
Procurement Notes
Verify the specific voltage tolerance and insulation class requirements against your system design before ordering. Confirm that the chassis mounting holes align with your enclosure specifications. Ensure the lead wire lengths meet your internal wiring constraints. Check for any regional compliance certifications required for your target market deployment.
Selection Notes
Select this component when a high-power toroidal solution is needed for fixed installations. The dual secondary configuration suits applications requiring balanced or split rail voltages. Consider the physical footprint constraints, as the cylindrical shape requires adequate clearance. This model is suitable where low electromagnetic interference is prioritized over compact surface-mount solutions.
Part Context
This part belongs to the VTX series of toroidal transformers manufactured by Vigortronix. These components are characterized by their round geometry and high efficiency compared to laminated cores. The series typically offers various VA ratings and voltage combinations tailored for robust power conversion tasks in stationary electronic equipment.
Replacement Considerations
Direct substitutes must match the 225 VA rating, 230V primary, and 2x18V secondary specifications. Verify dimensional compatibility, specifically the 50mm x 110mm profile, to ensure fit within existing chassis mounts. Lead wire gauge and length should be comparable to maintain electrical performance and mechanical stability.
