Details
Meanwell SCW20B Series is 20W isolated and regulated DC-DC converter. The product outstands module type and DIP24 package. At the same time, the main features are as following: international standard pins, high efficiency reaching up to 89%, wide working temperature range -40~+80℃,1.5KVDC I/P-O/P isolation voltage, Compliance to BS EN/EN55032 radiated Class A without extra components, continuous-mode short circuit protection, etc. Apart from them, the additional components models account for different input voltage 9~18V, 18~36V and 36~75V 2:1 wide input range, and various output voltage, 5V/12V/15V for single output. Considering its low cost, high reliability, and excellent quality, Meanwell SCW20B Series is suitable for all kinds of systems, such as industrial control,telecommunication field, distributed power architecture, and so on.
