Description
The Triad WDU9-100 is a compact plug-in AC/DC power supply designed for low-power electronics and industrial systems. Operating from a standard 120VAC input at 60Hz, it provides a steady 9VDC output with a maximum current of 100mA. The power supply features a thermoplastic molded case and a six-foot cord terminated with a 2.1mm center-positive barrel plug. Though it's an unregulated linear design—meaning voltage can rise to ~12.7V under no load—it’s well-suited for stable devices with modest power requirements such as sensors, measurement tools, or embedded circuits.
