F56-045

Overview

The Triad Magnetics F56-045 is a laminated core power transformer designed for board mount applications. It features a single primary winding rated at 115V and dual secondary windings configured in the Split Pack series. The unit provides two output options: a parallel connection delivering 28V at 90mA, or a series connection providing 56V at 45mA. With a maximum power rating of 2.5VA, it offers 2500Vrms isolation voltage. The component utilizes through-hole PC pin termination and measures 34.93mm in length, 28.58mm in width, and up to 30.15mm in height.

Feature Summary

• Dual secondary winding configuration allows flexible voltage selection via parallel or series connections.
• Laminated core construction supports standard industrial control power requirements.
• Provides 2500Vrms electrical isolation between primary and secondary circuits.

Applications

• Industrial control panel power supplies
• General purpose electronic equipment requiring isolated AC power
• Class 2/3 compliant low voltage circuit powering

Procurement Notes

Verify the specific package suffix when ordering, as variants such as F56-045-C2 exist with potential differences in mounting style or certification status. Confirm that the required current rating (45mA series or 90mA parallel) aligns with the load design. Check RoHS compliance documentation for environmental regulations relevant to the target market before finalizing procurement specifications.

Selection Notes

Select this model when a compact 2.5VA transformer is needed for 115V input systems. Ensure the application can accommodate the physical dimensions of approximately 35mm by 29mm. Choose the parallel secondary mode if higher current at lower voltage is required, or the series mode for higher voltage at reduced current. Verify that the chassis or PCB layout supports the through-hole pin spacing and height constraints.

Part Context

This component belongs to the Split Pack series from Triad Magnetics, which focuses on Class 2 and Class 3 power transformers. The F56 series specifically addresses needs for small form factor power conversion in industrial settings. It serves as a direct replacement for legacy Hammond Manufacturing part numbers like 164E56, maintaining compatibility with established industrial designs.

Replacement Considerations

Signal Transformer ST-3-56 is documented as a similar substitute part number. Cross-reference with Hammond Manufacturing part number 164E56 for equivalent functionality in existing designs. Verify pinout and dimensional compatibility before substituting to ensure proper integration into the target assembly.
