Details
Meanwell MFM-20-12 is a 20W AC/DC on board type medical grade power supply with 12V1.8A0-1.8A1.98A21.6W23.8W150mVp-p. The item is designed in high density and small size (49*23.8* 23mm). Moreover, it highlights the operation for 80~264VAC, low no load power consumption<0.1W, and high efficiency up to 87%. Additionally, MFM-20-12 is equipped with Class II (no FG) double insulation, extremely low leakage current, 5G anti-vibration, high EMC performance, 4KVAC isolation, etc. so it is able to fit IEC/BS EN/EN60601-1 and ANSI/AAMIES60601-1 version three. Besides them, MFM-20-12 has the complete protection functions such as Short circuit, Overload, Over voltage and Over temperature. In light of its longevity, high reliability, excellent quality, Meanwell MFM-20-12 is a very suitable solution for BF (patient contact) type medical device or relevant equipment.
