14A-56-16

Overview

The Signal Transformer 14A-56-16 is a laminated core power transformer designed for through-hole mounting. It features a single primary winding rated for 115VAC and 230VAC operation, configurable via parallel connections. The secondary side provides dual outputs with a center tap, delivering 8V at 7A in parallel mode or 16V at 3.5A in series mode. This component offers a maximum power rating of 56VA and includes 2500Vrms isolation voltage to ensure safety compliance in general-purpose power supply applications.

Feature Summary

• Laminated core construction for efficient magnetic flux transfer
• Dual secondary windings supporting flexible parallel or series configurations
• Through-hole termination style for robust PCB integration
• High isolation voltage rating for enhanced electrical safety

Applications

• General purpose AC/DC power supplies
• Industrial control equipment power stages
• Consumer electronics requiring isolated DC rails
• Audio amplifier power sections

Procurement Notes

Verify the specific datasheet version for the 14A series to confirm exact pinout assignments and mechanical tolerances before integration. Ensure that the input voltage configuration matches the required primary connection (parallel for 115V or series for 230V) as specified in the official documentation. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this model when a 56VA capacity is required with dual secondary voltages. The choice between 8V/7A and 16V/3.5A depends on the downstream rectification and regulation circuitry. Consider the physical dimensions and through-hole requirements against available PCB space. Verify that the operating temperature range aligns with the intended environment.

Part Context

This component belongs to the 14A Series from Signal Transformer, which focuses on high-power laminated transformers. The series is characterized by robust construction suitable for demanding industrial and commercial applications. It complements other models in the lineup that offer varying VA ratings and voltage configurations while maintaining consistent mounting and isolation standards.

Replacement Considerations

Direct substitutes within the same series may include parts with identical VA ratings but different secondary voltages. Cross-manufacturer replacements require matching the 56VA rating, 115V/230V primary capability, and 2500Vrms isolation. Always verify mechanical footprint compatibility and pin-to-pin electrical equivalence before substitution.
