F-357X

Overview

The F-357X is a chassis-mount industrial power transformer manufactured by Triad Magnetics. It features dual primary windings rated for 115V and 230V AC input at 50/60Hz frequencies. The unit provides a single center-tapped secondary output of 25.2V at 1A, resulting in a 25.2VA power rating. Designed for robust industrial applications, it utilizes wire leads for termination and supports Class 2 circuit configurations.

Feature Summary

• Dual primary winding configuration enables versatile operation across standard 115V and 230V AC supply networks.
• Single center-tapped secondary winding delivers precise voltage regulation for sensitive control circuits.
• Chassis mount construction with wire lead terminations facilitates secure integration into industrial enclosures.

Applications

• Industrial control panels requiring isolated low-voltage power distribution
• Automation systems utilizing 24V class components
• Equipment needing reliable step-down transformation from mains voltage

Procurement Notes

Verify the specific datasheet version to confirm compliance with current safety standards such as UL or CE. Ensure the chassis mounting holes align with your enclosure design before procurement. Confirm that the wire lead length meets your internal wiring requirements. Cross-reference the pinout diagram with your target PCB or terminal block layout to prevent installation errors during assembly.

Selection Notes

Select this component when a dedicated 25.2VAC source is required for control logic or relay coils. The dual primary design offers flexibility for global deployment without rewiring. Consider the physical dimensions and weight constraints of the installation space. Verify that the 1A current capacity suffices for the total load of downstream devices connected to the secondary circuit.

Part Context

This model belongs to Triad Magnetics' industrial power transformer series, characterized by laminated core construction and high reliability. These units are engineered for continuous duty in demanding environments. The F-series typically emphasizes durability and electrical isolation suitable for heavy machinery and automated manufacturing processes.

Replacement Considerations

Direct substitutes must match the 25.2VCT secondary specification and 25.2VA rating. Verify that alternative models support the same 115/230V dual primary input range. Ensure mechanical compatibility regarding chassis mounting footprint and terminal type. Consult manufacturer cross-reference lists for verified equivalent part numbers.
