F-3181U

Overview

The Triad Magnetics F-3181U is a chassis-mount industrial power transformer featuring a laminated core and split bobbin construction. It provides a single secondary output of 12.6V at 4.0A, delivering a 50VA power rating. The unit supports dual primary voltage inputs of 115VAC and 230VAC. Designed for robust performance, it utilizes wire leads for termination and is housed in a standard industrial enclosure suitable for panel integration.

Feature Summary

• Split bobbin design enhances electrical isolation between windings
• Laminated core structure ensures efficient magnetic flux transfer
• Dual primary winding configuration allows flexible voltage compatibility

Applications

• Industrial control panels requiring isolated power supplies
• Equipment needing 12.6V AC auxiliary power
• Chassis-mounted electronic enclosures

Procurement Notes

Verify the specific datasheet revision to confirm terminal finish specifications and exact dimensional tolerances. Ensure the receiving facility has adequate ventilation for the thermal characteristics associated with 50VA continuous operation. Confirm that the wire lead lengths meet the specific routing requirements of the target chassis assembly before final installation.

Selection Notes

Select this component when a dedicated 50VA isolation transformer is required for 115V or 230V systems. The split bobbin architecture is critical for applications demanding high dielectric strength between primary and secondary circuits. Consider the physical dimensions and wire lead orientation during the mechanical layout phase to ensure proper fit within the designated chassis space.

Part Context

This model belongs to the F series of industrial power transformers manufactured by Triad Magnetics. The series is characterized by chassis-mount designs intended for general-purpose industrial applications. These units typically feature laminated cores and are designed to replace legacy components in existing equipment architectures requiring reliable step-down or isolation capabilities.

Replacement Considerations

Direct substitutes must match the 50VA rating, 12.6V secondary output, and 115/230V primary input. Verify that alternative models maintain the same chassis mounting footprint and wire lead termination style to avoid mechanical redesign.
