Overview
The Signal Transformer 14A-5.0R-16 is a board-mount power transformer with a 5 VA rating, designed for through-hole installation. It features dual primary windings rated for 115 VAC and 230 VAC, and a dual secondary winding configuration providing 8.0 VCT at 0.31 A in parallel or 16.0 V at 0.31 A in series. The unit operates at 50/60 Hz and utilizes a laminated core construction.
Feature Summary
- Dual primary winding capability for versatile voltage input
- Configurable dual secondary outputs for flexible circuit design
- Laminated core construction for standard power applications
Applications
- General purpose AC to DC power supply circuits
- Industrial control panel power distribution
- Consumer electronics requiring isolated low-voltage AC
Procurement Notes
Verify the specific datasheet revision when ordering, as manufacturers may update pinouts or mechanical dimensions without changing the base model number. Confirm that the required secondary configuration (parallel vs. series) matches the PCB footprint and wiring scheme of the target application to ensure proper electrical integration.
Selection Notes
Select this component when a 5 VA isolation barrier is required between mains voltage and low-voltage loads. Ensure the operating frequency aligns with the 50/60 Hz specification. Consider the physical dimensions and through-hole mounting style against available board space and assembly constraints before finalizing the design.
Part Context
This part belongs to the 14A series of power transformers from Signal Transformer. These components are standardized laminated core units intended for general-purpose board mounting. The series offers various voltage configurations to support diverse global power standards while maintaining consistent mechanical form factors for easy replacement in existing designs.
Replacement Considerations
Direct substitutes include the 14A-5.0R-12 and 14A-5.0R-16# variants within the same series. Verify that alternative models match the 5 VA power rating and 115/230 VAC primary requirements. Mechanical compatibility must be confirmed if substituting with different secondary voltage options.
