Details
Meanwell RDDW20UW Series is 20W DC-DC reliable railway Converter. The product outstands module type and 2"x1"package. Meanwhile, the main features are as following: international standard pins, high efficiency reaching up to 89%, wide working temperature range -40~+95℃, 3KVAC I/P-O/P isolation voltage, and meet EN501 55 with external circuits, continuous-mode short circuit protection, etc. Apart from them, the models account for 8.5~160VDC 18:1 ultra-wide input range, and various output voltage, 5V/12V/15V for single output, and ±12V/±15V/±24 for dual outputs. Considering its high efficiency, excellent reliability and good performane, Meanwell RDDW20UW Series is suitable for railway, trams, buses, and also can be used in the harsh environment with high vibration, high dust, extremely low or high temperature, etc.
