Details
Meanwell RDDW20F-12 is 20W DC-DC reliable railway converter with 24V35mA947mA±12V±0~835mA. The unit features module type and 2"x1" package. At the same time, the main highlights are as following: international standard pins, high efficiency 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. Moreover, 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. In view of its longevity, high reliability, and excellent performane, Meanwell RDDW20F-12 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.
