Overview
The Pulse Electronics 14A-2.5-24B25 is a board-mount, through-hole laminated power transformer designed for low-frequency applications. It features a 2.5VA power rating with dual primary voltage ratings of 115 VAC and 230 VAC, providing a single secondary output of 24 V. The component utilizes PC pin termination and is constructed with a laminated core structure. It supports RoHS compliance standards and is intended for general-purpose power conversion tasks requiring reliable isolation between primary and secondary circuits.
Feature Summary
- Dual primary winding configuration supporting multiple input voltage standards
- Laminated core construction for efficient low-frequency magnetic coupling
- Through-hole mounting style with PC pin termination for secure board attachment
Applications
- Low-frequency power supply units
- Industrial control equipment isolation
- General purpose AC to DC power conversion stages
Procurement Notes
Verify the specific datasheet version before procurement, as manufacturer documentation may vary. Confirm that the dual primary voltage requirements match your circuit design. Ensure through-hole mounting capabilities are available on the target PCB. Check for any updated regulatory compliance statements regarding RoHS status in the latest official documentation.
Selection Notes
Select this component when a 2.5VA isolated transformer is required for 115V or 230V input systems. The fixed 24V secondary output limits flexibility but simplifies design for specific voltage rails. Consider physical dimensions of 41.28mm L x 33.32mm W for enclosure space planning. Through-hole technology is necessary for mechanical stability in high-vibration environments.
Part Context
This part belongs to the Pulse Electronics 14A series of laminated power transformers. These components are characterized by their robust through-hole construction and standardized voltage ratings. The series is commonly used in legacy and industrial designs where mechanical durability and simple isolation are prioritized over miniaturization.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing footprints and electrical specifications if considering alternative manufacturers.
