14A-2.5R-36

Overview

The Signal Transformer 14A-2.5R-36 is a single-phase power transformer designed for board mount applications. It features a primary voltage rating of 115/230 VAC and operates at frequencies of 50/60 Hz. The unit provides a secondary output of 36 VAC with a maximum power dissipation of 2.5 W. Key electrical specifications include a dielectric strength of 4000 Vrms. The component utilizes PC pin termination for through-hole mounting, ensuring secure integration into electronic circuits requiring isolated power conversion.

Feature Summary

• Single-phase laminated core construction for efficient power transfer
• Dual primary voltage capability supporting 115V and 230V inputs
• High dielectric strength insulation rated at 4000 Vrms
• Through-hole PC pin termination for reliable board integration

Applications

• Industrial control systems requiring isolated low-voltage power
• Servo drive power supply circuits
• Electronic equipment needing 36V AC auxiliary power

Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer notifications may update physical dimensions or material compositions. Confirm that the 2.5W power rating aligns with the thermal requirements of the target enclosure. Ensure the PCB footprint matches the PC pin spacing to prevent mechanical stress during assembly. Cross-reference the 4000 Vrms dielectric rating against safety standards applicable to the final product deployment region.

Selection Notes

Select this model when a compact, board-mount solution is required for converting standard line voltages to a stable 36V AC output. The dual primary winding allows flexibility in global markets without changing hardware. Consider the 2.5W limit carefully; if higher power is needed, larger chassis-mount alternatives from the same series should be evaluated. The through-hole format is suitable for prototyping and high-reliability environments where surface-mount solder joints may be insufficient.

Part Context

This component belongs to the Signal Transformer 14A series, which focuses on small-form-factor power transformers. These units are engineered for applications where space is constrained but isolation and reliability are critical. The series typically offers various voltage configurations to support diverse industrial and commercial electronics, providing a standardized interface for designers integrating isolated power stages.

Replacement Considerations

Direct substitutes must match the 115/230V primary, 36V secondary, and 2.5W power rating. Verify that any replacement maintains the 4000 Vrms dielectric strength and PC pin termination style. Check dimensional compatibility with existing PCB layouts to ensure mechanical fit.
