Meanwell MDS03G-12 is a 3W isolated and regulated DC-DC converter with 15mA160mA12V0-250mA. The unit features module type, and medical grade with DIP 24 package. Meanwhile, the main highlights are as following: international standard pins, high efficiency up to 81%, wide working temperature range -40~+90℃, 6KVDC or 4.2KVAC I/P-O/P high isolation voltage, compliance with IEC60601-1 medical standard, continuous-mode short circuit protection, etc. What’s more, MDS03G & MDD03G models account for different input voltage 9~36V and 18~75V 4:1 wide input range, and various output voltage: 5V/12V/15V for single output, and ±5V/±12V/±15V for dual output. Thanks to its high reliability, excellent quality, and competitive price, Meanwell MDS03G-12 is very suitable for medical systems requiring ultra-low leakage current.
