Procurement Notes
Verify that the specific 2 x 9VAC output requirement matches the system design before ordering. Confirm that the open style form factor fits within the available chassis space. Ensure that the thermal fuse ratings align with the safety standards of the final assembly. Cross-reference the part number with official distributor catalogs to confirm current availability and authenticity from authorized Vigortronix channels.
Selection Notes
Select this model when a 100VA capacity is required with a split secondary voltage. The dual winding design supports bridge rectifier configurations common in audio and industrial applications. Consider the physical dimensions of the toroidal shape for enclosure planning. Verify that the operating frequency matches the input source requirements. This component is suitable for environments where high efficiency and low electromagnetic interference are prioritized.
Part Context
This transformer belongs to the Vigortronix VTX-146 series, which specializes in toroidal power transformers. The series offers various VA ratings and voltage configurations to suit different power demands. The VTX-146-100-209 specifically addresses the need for moderate power handling with precise voltage splitting. It represents a standard solution for replacing older EI-core transformers with more compact and efficient toroidal alternatives.
Replacement Considerations
Consult cross-reference tools for parametrically similar parts if this specific variant is unavailable. Ensure any substitute maintains the 100VA rating and 2 x 9VAC output specification. Verify that the replacement also includes thermal fuse protection and meets EN61558 standards. Physical footprint compatibility must be confirmed before switching suppliers or models.
