Details
Meanwell RSDW20F Series is 20W DC-DC reliable railway converter. The product outstands module type and 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~+85℃, 1.5KVDC(F/G models)/3KVDC(H models) I/P-O/P isolation voltage, compliance with EN50155 railway standard, continuous-mode short circuit protection, etc. Apart from them, the models account for different input voltage 9~36V, 18~75V and 43~160V 4:1 wide input range, and various output voltage, 3.3V/5V/12V/15V for single output, and ±5V/±12V/±15V for dual outputs. Considering its longevity, high reliability, and excellent performane, Meanwell RSDW20F 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.
