Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm electrical specifications and physical dimensions. Ensure that the open style housing and terminal configuration match the target design requirements. Cross-reference with authorized distributors to validate authenticity and availability of current production batches.
Selection Notes
Select this model when dual isolated secondary outputs are required alongside standard dual-voltage primary input capabilities. The 120 VA rating suits applications needing moderate power handling with compact toroidal geometry. Consider the open construction for custom mounting solutions where enclosed transformers are unsuitable.
Part Context
This transformer belongs to the Vigortronix VTX series of toroidal components. These units are characterized by high efficiency and low electromagnetic interference compared to traditional laminated cores. The series supports various power ratings and voltage configurations for diverse industrial and consumer electronics needs.
Replacement Considerations
Consult official cross-reference tools for parametrically similar parts. Verify that substitute components match the 120 VA rating, 2x9V secondary configuration, and dual primary input specifications. Ensure thermal protection features are equivalent to maintain system safety standards.
