F4-48

Overview

The Triad Magnetics F4-48 is a laminated core industrial power transformer with a 6VA rating. It features a single primary winding rated for 115V and a single secondary winding providing 48V at 125mA. The unit includes a center tap on the secondary side and offers 2500VAC isolation voltage. Designed for chassis mounting, it utilizes quick connect terminals measuring 0.187 inches (4.7mm). Physical dimensions are 60.33mm in length, 31.75mm in width, and 34.93mm in height.

Feature Summary

• Laminated core construction for standard industrial power applications
• Single primary to single secondary configuration with center tap
• High isolation voltage capability of 2500VAC
• Quick connect terminal style for simplified wiring integration

Applications

• Industrial control panel power supplies
• Chassis-mounted equipment requiring isolated DC power rails
• General purpose low-voltage AC power distribution

Procurement Notes

Verify that the required secondary current does not exceed 125mA to prevent overheating. Confirm that the mounting hardware accommodates the specific chassis thickness and hole spacing defined by the component's physical footprint. Ensure the input voltage matches the 115V primary rating before installation. Check terminal compatibility with existing harness connectors to ensure proper engagement with the 0.187-inch quick connect lugs.

Selection Notes

Select this component when a compact, low-power solution is needed for 115V to 48V conversion. The 6VA rating limits its use to low-current control circuits rather than high-power loads. Consider the chassis mount style if space constraints favor vertical installation over PCB mounting. The center tap feature allows for dual polarity supply generation if required by the circuit design.

Part Context

This transformer belongs to the Quick Pack series from Triad Magnetics, which focuses on standardized industrial power components. It serves as a fundamental building block for creating isolated power sections within larger electronic systems. The laminated core design distinguishes it from toroidal alternatives, offering a different form factor suitable for specific enclosure layouts.
