Details
Meanwell MFM-20 Series is a 20W AC/DC on board type medical grade power supply. The entire series is designed in high density and small size (49*23.8* 23mm). At the same time, it features the operation for 80~264VAC, low no load power consumption less than 0.1W, and high efficiency reaching up to 87%. In addition, MFM-20 is equipped with Class II (no FG) double insulation, excellent dissipation, 5G anti-vibration, high EMC performance, 4KVAC isolation, etc. so it is able to observe IEC/BS EN/EN60601-1 and ANSI/AAMIES60601-1 version three. Apart from them, MFM-20 offers the complete protection functions such as Short circuit, Overload, Over voltage and Over temperature. Considering its longevity, high reliability, excellent quality, Meanwell MFM-20 Series is a very suitable solution for BF (patient contact) type medical device or relevant equipment.
