Overview
The Vigortronix VTX-146-160-218 is a 160 VA open-style toroidal transformer with dual primary windings supporting 115V and 230V input. It features a secondary output of 0-18VAC, configurable as parallel 18V or series 36V at full load. The unit includes thermal fuses for protection and holds UL approval. Designed for PCB mounting, it ensures stable voltage conversion in electronic equipment.
Feature Summary
- Dual primary winding configuration for flexible 115V/230V operation
- Integrated thermal fuse protection for enhanced safety
- UL approved construction ensuring compliance with safety standards
- Open style design optimized for direct PCB installation
Applications
- Electronic equipment requiring stable voltage conversion
- Power supply units utilizing PCB mounting
- Industrial control systems needing isolated power transformation
Procurement Notes
Verify the specific part number against official Vigortronix documentation to confirm compatibility with your circuit requirements. Ensure that the dual primary winding configuration matches your available input voltage source. Check for any updated regulatory certifications or packaging specifications directly from the manufacturer before finalizing procurement orders.
Selection Notes
Select this model when a 160 VA capacity is required with a 0-18V secondary output. The dual primary design allows adaptation to both 115V and 230V mains without rewinding. Consider the open style form factor if space constraints allow for non-enclosed mounting on a printed circuit board within the target assembly.
Part Context
This component belongs to the Vigortronix VTX-146 Series of toroidal transformers. The series is characterized by high-quality construction and reliability for general-purpose power transformation. The VTX-146-160-218 specifically denotes the 160 VA rating and the 218 suffix indicating the dual primary and specific secondary voltage configuration.
Replacement Considerations
Direct substitutes must match the 160 VA rating, 0-18V secondary output, and dual primary input capability. Verify physical dimensions and mounting hole patterns for PCB integration. Ensure equivalent thermal protection ratings and UL certification status are maintained during replacement.
