Overview
The Signal Transformer 14A-5.0R-24 is a board-mount power transformer featuring a laminated core design intended for through-hole mounting. It operates at standard frequencies of 50 Hz and 60 Hz with a power rating of 5 VA. The unit utilizes dual primary windings rated for 115 VAC and 230 VAC, configured in parallel. Secondary outputs provide dual configurations: parallel connection yields 12 VAC at 420 mA, while series connection provides 24 VAC at 210 mA. Physical dimensions are optimized for compact integration.
Feature Summary
- Dual primary winding configuration supporting multiple input voltage standards
- Flexible secondary output options allowing parallel or series connection
- Laminated core construction for efficient magnetic flux transfer
- Through-hole installation style for secure PCB attachment
Applications
- General purpose AC to DC rectification circuits
- Low-power industrial control panel power supplies
- Consumer electronic device internal power conversion
- Signal conditioning and isolation stages
Procurement Notes
Verify the specific secondary configuration required for your circuit design, as the part supports both parallel (12V) and series (24V) connections. Confirm that the 5 VA power rating meets the load requirements of the application. Ensure the through-hole footprint matches the PCB layout specifications before finalizing the order.
Selection Notes
Select this component when a compact, cost-effective solution for low-power isolation is needed. The dual primary capability simplifies global deployment by accommodating different mains voltages without changing hardware. Consider the physical size constraints and thermal environment, as the laminated core design may require adequate spacing for heat dissipation during continuous operation.
Part Context
This model belongs to the 14A series of power transformers from Signal Transformer. The series is characterized by standardized footprints and robust laminated core construction. These components are widely used in applications requiring reliable galvanic isolation between primary mains sources and secondary low-voltage loads.
Replacement Considerations
Direct substitutes within the same series include the 14A-5.0R-12 for 12V parallel output and the 14A-5.0R-24 for 24V series output. Verify pinout compatibility and mechanical dimensions when considering alternative manufacturers' equivalents.
