14A-56-12

Overview

The Signal Transformer 14A-56-12 is a laminated core power transformer designed for board mount applications. It features dual primary windings rated for 115 VAC and 230 VAC, providing versatile input compatibility. The secondary configuration offers parallel outputs of 6.3V at 8.8A or series outputs of 12.6V at 4.4A, delivering a maximum power rating of 56VA. This component utilizes through-hole PC pin termination for secure installation. Its physical dimensions are 76.20mm in length, 63.50mm in width, and a maximum height of 46.00mm. The unit provides 4000Vrms isolation voltage and operates within standard industrial temperature ranges.

Feature Summary

• Dual primary winding design supports both 115V and 230V AC input configurations
• Flexible secondary output options allow parallel 6.3V or series 12.6V operation
• Laminated core construction ensures stable power transformation performance
• High isolation voltage rating of 4000Vrms enhances electrical safety

Applications

• Industrial control panel power supplies
• General purpose equipment requiring isolated DC power
• Medical device internal power systems
• Automated machinery control circuits

Procurement Notes

Verify the specific datasheet version before ordering, as manufacturing locations and specifications may undergo changes documented in Product Change Notices. Confirm that the required lead time aligns with project schedules, as production cycles can extend significantly. Ensure the through-hole mounting style matches the target PCB layout constraints. Check RoHS compliance status if environmental regulations apply to the final assembly. Validate that the 56VA power rating meets the system's peak current demands without overheating.

Selection Notes

Select this model when a robust laminated transformer is needed for high-current applications up to 8.8A. The dual primary feature simplifies global deployment by accommodating different regional line voltages. Consider the physical footprint of 76.20mm x 63.50mm against available board space. The 4000Vrms isolation makes it suitable for sensitive medical or industrial environments requiring strict safety barriers. Compare thermal dissipation requirements against the 56VA rating to ensure adequate cooling.

Part Context

This component belongs to the One-4-All™ series from Signal Transformer, known for standardized form factors across various power ratings. The 14A series typically serves as a direct replacement for legacy transformers in existing designs. It is manufactured under Bel Fuse's Signal Transformer brand, ensuring consistent quality standards. The part is distinct from smaller signal transformers or larger chassis-mounted units due to its specific board-mount orientation and power class.

Replacement Considerations

Direct substitutes include models with identical 56VA ratings and matching pinout configurations. Verify that any replacement maintains the 4000Vrms isolation level and 115/230V primary compatibility. Ensure the secondary voltage and current capabilities meet or exceed the original 6.3V/8.8A or 12.6V/4.4A specifications. Physical dimensions must fit the existing mounting holes and clearance requirements.
