F-219X

Overview

The Triad Magnetics F-219X is a laminated core power transformer designed for industrial applications. It features a primary voltage of 115VAC and operates at frequencies of 50/60Hz. The secondary output provides 12VAC at 4A, resulting in a total apparent power rating of 48VA. This component utilizes a bobbin construction with wire leads and is intended for chassis mounting via flange. It offers an isolation rating of 1500Vrms between windings. The unit is UL certified and complies with RoHS standards, ensuring suitability for regulated electronic environments.

Feature Summary

• Laminated core construction for standard industrial power conversion
• Chassis mount design with integrated flange for secure installation
• High dielectric isolation capability between primary and secondary circuits
• Certified compliance with safety and environmental regulations

Applications

• Industrial control panel power supplies
• Equipment requiring isolated AC voltage step-down
• Chassis-mounted electronic enclosures
• General purpose industrial machinery power distribution

Procurement Notes

Verify the specific datasheet version to confirm insulation class and thermal ratings before integration. Ensure mechanical clearance matches the chassis mounting dimensions. Confirm that the 115V primary input aligns with the local supply voltage. Check for any recent regulatory updates regarding UL certification status. Validate lead length requirements against PCB or terminal block spacing constraints.

Selection Notes

Select this model when a 48VA capacity is required for 115V to 12V conversion. Consider the physical size constraints due to the chassis mount form factor. Evaluate if the laminated core efficiency meets system thermal requirements. Compare against toroidal alternatives if lower stray field emission is critical. Verify that the 4A secondary current rating covers peak load demands.

Part Context

This component belongs to Triad Magnetics' industrial power transformer lineup. It serves as a fundamental isolation stage in AC power systems. The F-series typically denotes standard laminated designs. It replaces older generic transformers where specific 12V outputs were needed. Availability is maintained through authorized distributors.

Replacement Considerations

Direct substitutes must match the 48VA rating, 115V primary, and 12V 4A secondary specifications. Verify identical chassis mounting hole patterns for mechanical compatibility. Ensure equivalent isolation voltage ratings are maintained. Cross-reference pinout configurations if lead arrangements differ. Consult manufacturer cross-reference lists for approved equivalents.
