Overview
The Triad Magnetics F-157XP is a laminated core power transformer designed for chassis mounting. It features a single primary winding rated for 115VAC input and dual secondary windings providing parallel 20V or series 40V outputs. The unit has a power rating of 7.5 VA with a maximum output current of unspecified amperage in the provided text, though typically associated with specific load conditions. It utilizes wire leads for termination and includes flanges for secure installation.
Feature Summary
- Laminated core construction for efficient magnetic coupling
- Single primary winding configuration for standard voltage inputs
- Dual secondary windings allowing flexible parallel or series connection options
- Chassis mount design with integrated flanges for stable physical attachment
Applications
- Industrial control systems requiring isolated power supply
- Electronic equipment needing 20V or 40V AC secondary rails
- Audio amplifier circuits utilizing split or combined secondary voltages
- General purpose power transformation in chassis-mounted enclosures
Procurement Notes
Verify the specific lead time requirements as manufacturing cycles may vary. Confirm that the chassis mounting dimensions and flange spacing align with your enclosure design. Ensure the input voltage matches the 115VAC specification before integration. Check for any regional compliance certifications required for your target market deployment.
Selection Notes
Select this model when a 7.5 VA capacity is sufficient for the load. Choose the F-157XP if chassis mounting is preferred over PCB surface mount alternatives. Consider the dual secondary flexibility if both 20V parallel and 40V series configurations are needed within the same project scope. Verify that the wire lead termination style suits the wiring harness design.
Part Context
This component belongs to the Triad Magnetics F series of industrial control transformers. It is distinct from the FP series which offers flat pack PCB mounting solutions. The F-157XP shares the chassis mount form factor with models like the F-3117X but differs in power rating and voltage configuration. It serves as a dedicated power isolation device rather than an audio or signal transformer.
Replacement Considerations
No direct public substitute part numbers are confirmed in the provided documentation. Users should verify electrical compatibility with similar Triad Magnetics models such as the F-152XP if pinout or mounting differences exist. Cross-referencing datasheets is essential to ensure voltage and current ratings match the application requirements.
