Procurement Notes
Verify the specific ordering suffix against official documentation to ensure correct electrical characteristics. Confirm that the 117V primary rating aligns with your system voltage requirements. Check datasheet specifications for thermal limits and mechanical mounting constraints before integration. Ensure compliance with relevant safety standards for the intended deployment environment.
Selection Notes
Select this component when a 16.8 VA capacity is required for 117V input systems. The 24V center-tapped secondary is appropriate for circuits needing dual polarity or rectification. Consider the chassis mount style and wire lead termination method for enclosure design. Evaluate the physical footprint and weight against available space and structural support capabilities.
Part Context
This model belongs to the Hammond 166 series of industrial control transformers. These units are characterized by laminated core construction and robust performance for general-purpose power transformation. The series offers various voltage and wattage options to suit different industrial control needs while maintaining consistent mounting and termination styles.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 16.8 VA rating, 117V primary, and 24V CT secondary specifications. Verify identical mounting dimensions and terminal types to maintain compatibility.
