FS28-085-C2

Power Transformers Overview

The Triad Magnetics FS28-085-C2 is a power transformer with a 2.5VA rating, designed for through-hole mounting on printed circuit boards. It features a laminated core and split bobbin construction. The primary winding supports 115V or 230V AC input at 50Hz/60Hz frequencies. Secondary outputs provide 28VDC at 85mA and 14VDC at 170mA. The unit withstands up to 4200Vrms insulation voltage.

Power Transformers Feature Summary

• Split bobbin design for versatile PCB applications
• Dual secondary voltage outputs for flexible power distribution
• Laminated core construction for efficient magnetic coupling

Power Transformers Applications

• Industrial control systems requiring isolated DC rails
• Electronic equipment needing dual voltage supply
• Power supplies for low-voltage signal processing circuits

Power Transformers Procurement Notes

Verify the specific ordering suffix matches the required electrical parameters before purchase. Confirm that the through-hole package dimensions align with the target PCB layout. Ensure the insulation voltage rating meets safety standards for the intended application environment. Cross-reference part numbers carefully as suffixes may indicate minor variations in packaging or certification.

Power Transformers Selection Notes

Select this component when a compact, dual-output power transformer is required for chassis or panel mounting via PCB. Consider the 2.5VA power limit and specific secondary voltages. Evaluate thermal performance within the enclosure. Compare against similar FS series models if different output configurations are needed.
