Overview
The Signal Transformer 14A-10R-12 is a board-mount power transformer with a 10 VA rating. It features dual primary windings supporting 115 VAC and 230 VAC inputs, configurable in parallel or series. The secondary provides dual outputs of 6.3 V and 12.6 V, also configurable for parallel (1.6 A) or series (800 mA) operation. Designed for through-hole mounting, it operates at 50/60 Hz. Dimensions are approximately 41.3 mm length, 36.5 mm width, and 34.9 mm height.
Feature Summary
- Dual primary and secondary winding configurations allow flexible voltage input and output arrangements.
- Laminated core construction supports standard industrial frequency operations.
- Through-hole mounting style facilitates direct PCB integration.
Applications
- Industrial control panels requiring isolated power conversion
- General-purpose equipment power supplies
- Electronic systems needing 115V/230V AC input adaptation
Procurement Notes
Verify the specific datasheet version to confirm exact dimensional tolerances and insulation class ratings. Ensure the application circuit matches the required primary and secondary configuration options. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference pinout diagrams during PCB layout to prevent installation errors.
Selection Notes
Select this component when a 10 VA isolation transformer is needed for board-level mounting. It is suitable for designs requiring both 115 VAC and 230 VAC input compatibility without manual rewiring. Choose this model over chassis-mounted alternatives when space constraints on the printed circuit board are critical.
Part Context
This part belongs to the 14A series of laminated power transformers from Signal Transformer. The series offers various power ratings and voltage combinations. The 14A-10R-12 specifically addresses applications requiring moderate power isolation with flexible voltage stepping capabilities for standard mains frequencies.
Replacement Considerations
The Hammond Manufacturing 183G12 is documented as a similar replacement option. Verify that the substitute meets the same 10 VA rating and physical footprint requirements before implementation.
