14A-2.5R-24

Overview

The Signal Transformer 14A-2.5R-24 is a laminated power transformer designed for board mount applications, operating at 50/60 Hz frequencies. It features a 2.5 VA power rating with a single primary winding rated for 115 VAC input. The unit provides dual secondary voltages of 12 VAC and 24 VAC via PC pin through-hole termination. Key electrical specifications include a high potential isolation of 4000 Vrms between windings. The component measures 41.30 mm in length and 36.50 mm in width, utilizing the One-4-All series design for industrial control integration.

Feature Summary

• Dual secondary voltage outputs providing both 12 VAC and 24 VAC from a single unit
• High potential isolation capability of 4000 Vrms for enhanced safety
• Through-hole PC pin mounting style suitable for standard PCB assembly

Applications

• Industrial control panels requiring multiple low-voltage DC supplies
• Power supply circuits for electronic equipment needing 12V and 24V rails
• General purpose AC to AC step-down applications in control systems

Procurement Notes

Verify the specific datasheet version for the 14A-2.5R-24 to confirm terminal configuration and insulation class requirements. Ensure the PCB footprint matches the PC pin spacing dimensions provided in the official mechanical drawings. Confirm that the 2.5 VA rating meets the load current demands of the connected circuitry under all operating temperature conditions.

Selection Notes

Select this component when a compact transformer is needed to generate two distinct secondary voltages from a single 115 VAC source. The 4000 Vrms isolation makes it suitable for applications requiring strict separation between primary mains and secondary control circuits. Consider the through-hole mounting requirement and verify that the physical dimensions fit within the designated enclosure space.

Part Context

This part belongs to the One-4-All series by Signal Transformer, which focuses on versatile, general-purpose transformers for industrial markets. The series emphasizes standardized footprints and reliable performance for control panel builders. The 14A-2.5R-24 specifically addresses the need for multi-tap secondary outputs in space-constrained designs.

Replacement Considerations

Check for direct substitutes within the One-4-All series or other Signal Transformer laminated transformers with matching 2.5 VA ratings and dual secondary outputs. Verify that any replacement maintains the 4000 Vrms isolation rating and compatible PC pin pitch to ensure mechanical interchangeability without PCB redesign.
