Overview
The Triad F-270X is a chassis-mount power transformer engineered for industrial electronics, audio/video equipment, and control circuits. This transformer steps down 115VAC primary voltage to 40VCT (center-tap) secondary output at 1.0A, supporting both 50Hz and 60Hz operation for global deployment. The center-tap secondary configuration enables flexible rectification options for power supply designs.
