Procurement Notes
Verify the specific part number against official Hammond Manufacturing documentation to confirm electrical ratings and physical dimensions. Ensure the application environment remains within the specified operating temperature range of 0°C to +130°C. Confirm that the chassis mounting style and wire lead termination method align with the system design requirements before finalizing procurement.
Selection Notes
Select this component when a compact, low voltage transformer is required for chassis installation. The 115V primary input suits standard North American power distribution systems. The 24 VA rating and 2A current capacity define the maximum load capabilities. Verify that the center-tapped secondary configuration matches the downstream rectification or regulation circuit design needs.
Part Context
This model belongs to the Hammond 166 series of industrial control transformers. The series provides various power ratings and voltage configurations for general industrial use. The 166LA12 specifically addresses applications needing 115V to 12V conversion with a center-tapped secondary output.
Replacement Considerations
Consult Hammond Manufacturing catalogs for alternative part numbers within the 166 series offering different voltages or power ratings. Cross-reference specifications carefully to ensure compatibility with existing wiring and mounting constraints.
