MEAN WELL EPP-120S Open-Frame Power Supplies
MEAN WELL EPP-120S Open-Frame Power Supplies are 120W, highly-reliable, PCB-type, miniature power supplies with a 3" x 2" footprint. These power supplies operate within an 80VAC to 264VAC input voltage range and provide an output voltage from 12V to 48V. The EPP-120S power supplies are designed to be used with both Class I (with FG) and Class II (no FG) system designs. These power supplies feature short-circuit, overload, over-voltage, or over-temperature protections. The EPP-120S connectors offer up to 94% efficiency and less than 0.3W no-load power consumption. Typical applications include industrial automation machinery, industrial control systems, mechanical/electrical equipment, electronic instruments, equipment, and apparatus.Features
