FD4-120

Power Transformers Overview

The Triad Magnetics FD4-120 is a laminated core power transformer designed for chassis mounting. It features dual primary windings supporting 115V and 230V AC inputs, providing versatile compatibility with global power standards. The single secondary winding delivers a nominal output of 10V at 600mA, resulting in a maximum power rating of 6VA. This component utilizes quick connect termination pins for efficient PCB integration. Key electrical specifications include a dielectric isolation voltage of 2500VAC between windings. The unit measures approximately 65.07mm in length and 31.75mm in width, fitting standard industrial form factors.

Power Transformers Feature Summary

• Chassis mount construction with quick connect termination for simplified assembly
• Dual primary winding configuration enabling operation on both 115V and 230V AC lines
• Laminated core design providing reliable step-down voltage transformation

Power Transformers Applications

• Industrial control panel power supplies
• General purpose low-voltage AC equipment
• Consumer appliance internal power stages

Power Transformers Procurement Notes

Verify the specific suffix or variant code when ordering to ensure correct pinout and voltage ratings. Confirm that the receiving facility accepts quick-connect terminations rather than through-hole leads. Check regulatory compliance documentation for target markets, as certifications may vary by region. Ensure the application environment supports the thermal characteristics of a 6VA laminated transformer without forced cooling.

Power Transformers Selection Notes

Select this model when a compact, cost-effective solution for low-power AC conversion is required. The dual primary input eliminates the need for manual voltage selection switches in global products. Consider the physical dimensions against available chassis space. Verify that the 6VA output capacity meets the peak load requirements of the downstream circuitry, accounting for inrush currents and temperature derating.

Power Transformers Part Context

This component belongs to the Triad Magnetics Quick Pack series, which focuses on small form-factor transformers. The series offers various voltage and current combinations tailored for general-purpose applications. The FD4-120 specifically addresses the need for 10V secondary outputs in systems requiring moderate isolation and robust mechanical mounting via flange or chassis screws.

Power Transformers Replacement Considerations

Direct substitutes include the F4-120 variant from the same manufacturer family. Cross-reference with other manufacturers offering 6VA laminated transformers with identical 115/230V primary and 10V secondary specifications. Ensure replacement parts match the 7-pin quick connect termination style and 2500VAC isolation rating to maintain system safety and connectivity.
