Overview
The Hammond Manufacturing 160D120 is a low voltage power transformer designed for printed circuit board (PCB) mounting. It features a laminated core construction with dual primary windings supporting 115V and 230VAC inputs in parallel configuration. The secondary output provides a center-tapped arrangement, delivering 60VAC in parallel or 120VAC in series configurations. The unit has a rated capacity of 1VA, with a secondary current rating of 8mA per tap (16mA total parallel).
Feature Summary
- Dual primary winding design allows flexible input voltage selection between 115V and 230VAC.
- Center-tapped secondary output enables versatile voltage configuration options.
- Laminated core construction ensures efficient power transformation for low voltage applications.
Applications
- Low voltage PCB mounting in industrial control systems
- Power supply units requiring isolated AC voltage steps
- Equipment utilizing 60V or 120V center-tapped secondary circuits
Procurement Notes
Verify the specific secondary configuration requirement (parallel vs. series) against the application schematic before procurement. Confirm that the 1VA power rating and 8mA/16mA current limits are sufficient for the load. Ensure the PCB footprint matches the physical dimensions of the 160D120 component to avoid assembly issues.
Selection Notes
Select this model when a compact, board-mount transformer is required for 115V or 230VAC input conversion. It is suitable for applications needing a center-tapped secondary output at low power levels. Consider the physical size constraints and thermal requirements associated with a 1VA open-frame transformer design.
Part Context
This component belongs to the Hammond Manufacturing line of power transformers. It is categorized as an open-frame, low voltage transformer intended for direct integration into electronic assemblies. The part serves as a step-down or isolation device within larger electrical systems.
Replacement Considerations
Direct substitutes must match the 1VA rating, 115/230V primary, and 60-120V center-tapped secondary specifications. Verify pinout compatibility and physical mounting hole alignment to ensure interchangeability without redesigning the PCB layout.
FAQ
What is the secondary voltage configuration?
The secondary is center-tapped, providing 60VAC in parallel or 120VAC in series.
Can the primary be connected to 230VAC?
Yes, the dual primary windings support both 115V and 230VAC input via parallel connection.
