Details
Meanwell SCWN03A Series is 3W 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 87%, wide working temperature range -40~+90℃, 3KVDC I/P-O/P isolation voltage, Compliance to BS EN/EN55032 radiated Class A without additional components, continuous-mode short circuit protection, etc. Apart from them, the extra components,models account for different input voltage: 4.5~9V, 9~18V, 18~36V and 36~72V 2:1 wide input range, and various output voltage, 3.3V/5V/12V/15V for single output, and ±5/±12/±15 for dual outputs. Considering its competitive cost, high quality, and excellent reliability, Meanwell SCWN03A Series is suitable for all kinds of systems, such as industrial control, telecommunication field, distributed power architecture, and so on.
