F-243U

Overview

The Triad Magnetics F-243U is an industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115V AC and dual secondary windings providing 18.0V CT at 4.0A each. The unit has a total power rating of 230VA, with quick connect lugs for termination. Operating within a temperature range of -20°C to +105°C, it measures 6.75 inches in length, 3.69 inches in width, and 2.25 inches in height. The transformer weighs approximately 1.7 lbs and complies with UL/cUL safety standards.

Feature Summary

• Dual secondary windings provide independent 18.0V CT outputs for flexible circuit design
• Chassis mount construction with integrated lugs ensures secure mechanical installation
• High thermal endurance supports operation up to 105°C for demanding environments

Applications

• Industrial control panel power supplies
• Equipment requiring isolated dual voltage rails
• Heavy-duty machinery control circuits

Procurement Notes

Verify that the specific application requires dual 18V CT outputs rather than a single higher current configuration. Confirm chassis mounting space accommodates the physical dimensions of 6.75 x 3.69 x 2.25 inches. Ensure the enclosure allows for adequate airflow to maintain safe operating temperatures under full load conditions.

Selection Notes

Select this model when dual isolated secondary voltages are required from a single transformer core. The 230VA rating supports high-current applications compared to lower-rated alternatives. Consider the chassis mount style if panel integration is preferred over PCB or bracket mounting solutions.

Part Context

This component belongs to Triad Magnetics' industrial power transformer lineup. It serves as a step-down solution converting standard line voltage to lower control voltages. The design prioritizes durability and thermal stability for continuous operation in industrial settings.

Replacement Considerations

No direct substitute part numbers are publicly confirmed for this specific model. Evaluate transformers with matching 230VA ratings and dual 18V CT secondary configurations for potential functional equivalents.
