Details
Meanwell MFM-20-3.3 is a 20W AC/DC on board type medical grade power supply with 3.3V4.5A0-4.5A4.95A14.9W16.3A150mVp-p. The product is designed in high density and small size (49*23.8* 23mm). Meanwhile, it highlights the operation for 80~264VAC, low no load power consumption, and high efficiency up to 87%. Additionally, MFM-20-3.3 is equipped with Class II (no FG) double insulation, excellent dissipation, 5G anti-vibration, high EMC performance, 4KVAC isolation, etc. so it could observe IEC/BS EN/EN60601-1 and ANSI/AAMIES60601-1 version three. Moreover, the item offers the complete protection functions such as Short circuit, Overload, Over voltage and Over temperature. Thanks to its longevity, high reliability, excellent quality, Meanwell MFM-20-3.3 is a very suitable solution for BF (patient contact) type medical device or relevant equipment.
