F-268U

Overview

The Triad Magnetics F-268U is a laminated core power transformer designed for chassis mounting. It features a single primary winding rated at 115VAC with support for 50/60Hz frequencies. The secondary output provides 35VCT at 8A, delivering a maximum power capacity of 280VA. The unit utilizes wire leads for connection and includes flange mount hardware. Electrical insulation is rated at 1500Vrms between primary and secondary windings. Physical dimensions are approximately 107.95mm x 95.25mm x 114.3mm.

Feature Summary

• Laminated core construction for efficient power transformation
• 100% hipot tested ensuring 1500Vrms insulation integrity
• UL recognized Class B (130°C) rated materials
• Chassis mount design with integrated flange hardware

Applications

• Industrial control systems requiring isolated power
• Audio equipment power supplies
• General purpose AC to AC voltage conversion
• Equipment needing 35VCT secondary output

Procurement Notes

Verify the specific lead configuration and flange hole pattern against your mechanical enclosure requirements before ordering. Confirm that the 115V primary rating matches your local mains supply frequency and voltage standards. Ensure the 280VA thermal rating accommodates continuous load conditions without exceeding the Class B temperature limit. Cross-reference the physical footprint dimensions to guarantee proper clearance within the assembly.

Selection Notes

Select this component when a robust, high-power laminated transformer is required for chassis-mounted applications. The 280VA rating supports substantial current loads compared to smaller toroidal alternatives. Consider the physical size constraints as the chassis mount style requires specific panel cutouts. This model is suitable where standard isolation and UL recognition are mandatory for safety compliance in industrial or commercial environments.

Part Context

The F-268U belongs to Triad Magnetics' line of general-purpose power transformers. These units are engineered for reliability in demanding electrical environments. The series typically offers various voltage configurations and power ratings to suit different system architectures. Chassis mounting ensures stable mechanical performance during operation.

Replacement Considerations

Direct substitutes must match the 280VA power rating, 115V primary, and 35VCT secondary specifications. Verify identical physical dimensions and mounting hole patterns to ensure compatibility with existing enclosures. Check that replacement units maintain the same 1500Vrms insulation rating and UL Class B material classification.
