Overview
The Signal Transformer 14A-10R-28 is a laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115V and 230V input, supporting parallel configuration. The secondary side offers dual windings providing 14V or 28V output in parallel or series configurations respectively. Maximum current ratings are 720mA in parallel and 360mA in series. The unit has a 10VA power rating, operates at 50/60 Hz, and provides 4000Vrms isolation voltage. Physical dimensions are 47.6mm length, 39.7mm width, and 34.9mm height.
Feature Summary
- Dual primary and secondary winding architecture for flexible voltage configuration
- Laminated core construction for standard power transformation applications
- Through-hole termination style for printed circuit board integration
Applications
- General purpose AC to DC power supply circuits
- Industrial control panel power distribution
- Electronic equipment requiring isolated low voltage DC rails
Procurement Notes
Verify the manufacturer designation carefully, as this component is associated with both Bel Fuse and Signal Transformer branding in distributor catalogs. Confirm the specific datasheet version matches the required electrical tolerances and physical footprint before finalizing procurement orders to ensure compatibility with existing design specifications.
Selection Notes
Select this model when a 10VA laminated transformer is required with dual primary flexibility for global voltage inputs. Ensure the PCB layout accommodates the specific through-hole pin spacing and overall envelope dimensions. Consider thermal management requirements based on the full load current ratings of 720mA parallel or 360mA series operation.
Part Context
This component belongs to the general category of board-mount power transformers. It serves as a fundamental energy conversion element in electronic systems, stepping down mains voltage to safer, usable levels for downstream rectification and regulation stages within consumer or industrial electronics.
Replacement Considerations
The 183F28 by Hammond Manufacturing is listed as a similar substitute part number.
