LITEON Power 250W to 1200W Industrial ATX Power Supplies
LITEON Power 250W to 1200W Industrial ATX Power Supplies are designed in compliance with Intel® ATX 3.1 standards. These power supplies feature a 90VAC to 264VAC wide AC input voltage range (withstand 300VAC surge for 5s) and meet 80 PLUS Gold/Platinum high-efficiency levels. The 250W to 1200W ATX power supplies deliver high‑reliability AC‑DC power solutions and support 150% peak power capability for demanding industrial workloads. These power supplies offer flexible mechanical options, ranging from standard ATX to 1U Flex‑ATX, to ensure stable operation in harsh industrial environments up to 5000m altitude. Protection features include short-circuit, overcurrent, overvoltage, and overtemperature. Typical applications include IPC, embedded computer systems, factory automation, process control stations, machine vision, AI edge systems, networking, communication, and data processing equipment.
