F-255X

Overview

The Triad Magnetics F-255X is a laminated core power transformer designed for chassis mounting. It features a single secondary winding configuration with wire lead termination. The unit operates with a primary voltage of 115V and provides a secondary output of 20.0V at 2.0A, resulting in a maximum power rating of 40VA. The transformer includes a 1500Vrms isolation voltage rating. Physical dimensions are optimized for standard industrial control enclosures, utilizing a flange mount style for secure installation.

Feature Summary

• Laminated core construction for efficient power transfer
• Single secondary winding topology
• Chassis mount design with wire leads
• High isolation voltage capability

Applications

• Industrial control panel power supplies
• Audio equipment power stages
• Electronic test instrument internal power
• General purpose AC to DC rectifier input

Procurement Notes

Verify the specific datasheet version prior to ordering, as manufacturer specifications may undergo revision. Confirm that the 115V primary rating matches your local supply network frequency and voltage standards. Ensure mechanical clearance accommodates the chassis mount footprint and wire lead routing requirements within the target enclosure design.

Selection Notes

Select this component when a 40VA capacity is required for low-voltage secondary applications. The 20V output suits circuits requiring moderate current delivery up to 2A. Consider the chassis mount form factor if space constraints preclude PCB-mounted alternatives. Validate that the 1500Vrms isolation meets safety regulatory requirements for the intended end-use environment.

Part Context

This model belongs to the Triad Magnetics F-series of industrial control transformers. These units are engineered for durability in demanding environments. The F-255X specifically addresses needs for higher current single-phase power conversion. It complements other series variants offering different voltage taps or power ratings for broader system integration options.

Replacement Considerations

Direct substitutes must match the 40VA rating, 20V secondary output, and chassis mount style. Verify pinout compatibility and physical envelope dimensions before swapping. Alternative models from other manufacturers require validation of insulation class and thermal performance characteristics.
