Details
Meanwell MDS20B Series is a 20W isolated regulated DC-DC converter. The product outstands module type and medical grade with 2"x1"package. At the same time, the main features are as following: international standard pins, high efficiency reaching 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. What's more, 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. Considering its longevity, excellent quality and high reliability, Meanwell MDS20B Series 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.
