F-135P

Overview

The Triad Magnetics F-135P is a power transformer featuring a laminated core and single primary winding. It supports a 115VAC primary input voltage. The secondary configuration provides dual windings rated at 27V in parallel or 54V in series, with corresponding maximum currents of 56mA and 28mA respectively. Rated for 1.5VA, it utilizes PC pin through-hole termination and offers 1500Vrms isolation.

Feature Summary

• Single primary winding design for standard 115VAC line applications
• Dual secondary windings allowing flexible 27V parallel or 54V series output configurations
• High isolation rating of 1500Vrms between primary and secondary circuits
• PC pin through-hole mounting style suitable for printed circuit board integration

Applications

• Industrial control equipment requiring low-voltage DC power supplies
• Medical devices necessitating high isolation standards
