Details
Meanwell SKMW20F Series is 20W isolated and regulated DC-DC Converter. The product outstnads module type and DIP 1"x1"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~+85℃, 1.5KVDC I/P-O/P isolation voltage, Compliance to BS EN/EN55032 radiated Class A without additional components, Continuous-mode short circuit, overload, over temperature, input undervoltage protection, remote ON/OFF and trimmable output voltage etc. Apart from them, the models account for different input voltage 9~36V and 18~75V 4:1 ultra-wide input range, and various output voltage, 3.3V/5V/12V/15V for single output, and ±12V/±15V for dual outputs. Considering its longevity, high reliability, and excellent performance, Meanwell SKMW20F Series is suitable for all kinds of systems such as industrial control, telecommunication field, distributed power architecture, and so on.
