Details
Meanwell RDDW40F-12 is 40W DC-DC reliable railway Converter with 24V15mA1.95A±12V0-±1.666A. The model outstands module type and 2"x1" package. At the same time, the main features are as following: international standard pins, high efficiency up to 92%, wide working temperature range -40~+90℃, 1.6KVDC (F/G models)/3KVDC (H models) I/P-O/P isolation voltage, compliance with EN50155 railway standard, continuous-mode short circuit protection, etc. Additionally, the models account for different input voltage 9~36V, 18~75V and 40~160V 4:1 wide input range, and various output voltage, 3.3V/5V/12V/15V/24V/48V for single output, and ±12V/±15 for dual outputs. In light of its high efficiency, excellent reliability, and good performane, Meanwell RDDW40F-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.
