Details
Meanwell MDS20B-12 is a 20W isolated regulated DC-DC converter with 7mA1000mA12V1670mA. The item outstands module type and medical grade with 2"x1"package. Meanwhile, the main features are as following: international standard pins, high efficiency up to 90%, wide working temperature range -40~+90℃, 4KVAC I/P-O/P high isolation voltage, compliance with IEC60601-1 medical standard, and continuous-mode short circuit protection, etc. Furthermore, MDS20B models account for different input voltage 9~18V, 18~36V and 36~75V 2:1 wide input range, and various output voltage 5V/12V/1 5V/24V. Thanks to its longevity, excellent quality and high reliability, Meanwell MDS20B-12 is ideal for medical systems, which require high system insulation and reduced leakage current, thereby improving overall system safety and avoiding the risk of electric shock to patients.
After launching MDS01/02 module medical grade DC/DC converters, Meanwell extends MDS15/20 with 15W/20W. Therefore, it has a very full range of AC/DC power supply products, enriching medical-grade DC-DC converters, regardless of AC/DC or DC/DC power supply, Meanwell can provide complete power supply products and services, which can fully meet AC/DC+DC/DC two-stage design requirements on the system side.
