14A-20-515

Overview

The Signal Transformer 14A-20-515 is a single-phase power transformer designed for board mount applications. It features a laminated core construction and supports operating frequencies of 50 Hz and 60 Hz. The unit has a power rating of 20 VA with primary voltage ratings of 115 VAC and 230 VAC. Secondary outputs provide 5 VDC and ±15 VDC. It utilizes PC pin through-hole termination and offers a dielectric strength of 4000 Vrms.

Feature Summary

• Single-phase laminated core design for standard AC frequency operation
• Dual secondary output configuration providing multiple DC voltage levels
• Through-hole PC pin mounting for secure board integration
• High dielectric isolation strength between windings

Applications

• Industrial control panel power supplies
• Electronic equipment requiring isolated low-voltage DC rails
• General-purpose AC to DC conversion circuits
• Chassis-mounted or PCB-integrated power systems

Procurement Notes

Verify the specific secondary voltage configuration matches system requirements, as dual outputs are present. Confirm that the through-hole PC pin pitch aligns with the target printed circuit board layout. Ensure the 20 VA power rating provides sufficient headroom for the intended load current at both voltage rails. Check datasheet specifications for thermal derating curves if operating in enclosed environments.

Selection Notes

Select this component when a compact, board-mount solution is needed for converting standard line voltages to multiple low-voltage DC outputs. The 20 VA rating suits moderate power applications where space is constrained compared to chassis-mount alternatives. Consider the physical dimensions and terminal style during mechanical design to ensure compatibility with the assembly process and enclosure constraints.
