Open Frame

Discover high-performance open frame power supplies engineered for seamless integration into medical devices, industrial control systems, telecommunications equipment, and test instrumentation . Unlike enclosed units, these bare board power supplies feature a minimalist PCB-on-frame construction that allows OEMs to mount them directly into end equipment, optimizing space utilization and thermal management. Power ratings span from 30W to 1800W with output voltages of 5V, 12V, 15V, 24V, 36V, 48V, and 54V DC . Many models follow industry-standard footprints including 2" x 4" (up to 250W), 3" x 5" (up to 550W), and 4" x 8" (up to 650W), simplifying mechanical design .
