Procurement Notes
Verify the specific part number against official Vigortronix documentation to ensure compatibility with your circuit design. Confirm that the 230V primary and 0-18V dual secondary specifications match your system requirements. Check for any recent updates to safety compliance standards such as EN60950 or EN60065 before finalizing procurement decisions.
Selection Notes
Select this component when a compact toroidal transformer is required for 30VA applications. Ensure the input voltage matches the 230V AC specification. Consider the dual secondary configuration if separate isolated outputs are needed. Verify that the open style fits within the available enclosure space.
Part Context
This model belongs to the Vigortronix VTX series of PCB installation transformers. The series is designed for integration into electronic devices where stable voltage conversion is critical. The VTX-146-030-118 specifically addresses needs for moderate power handling with dual output capabilities in a standard toroidal form factor.
Replacement Considerations
Direct substitutes include other 30VA toroidal transformers with matching 230V primary and 0-18V dual secondary specifications. Ensure replacement units maintain similar physical dimensions and lead lengths for board compatibility.
