MEAN WELL RPS-120S Reliable Green Medical Power Supplies

MEAN WELL RPS-120S Reliable Green Medical Power Supplies are 120W PCB-type medical power supplies with a high power density on a 3" x 2" footprint. The power supplies accept 80VAC to 264VAC input with output voltages between 12V and 48V. The power supplies feature a working efficiency of up to 94%, low no-load power consumption below 0.3W, and less than 150µA leakage current. MEAN WELL RPS-120S medical power supplies can be used for both Class I (with FG) and Class II (no FG) system designs while conforming to international medical regulations (2xMOPP) and EMC EN55011. The devices are ideal for various BF-rated "patient contact" medical system equipment, such as oral irrigators, hemodialysis machines, and sleep apnea devices.
