Details
Meanwell RDDW08G Series is 8W DC-DC reliable railway converter. The item stands out with module type and DIP24 package. Meanwhile, the main features are as following: international standard pins, high efficiency reaching up to 86%, wide working temperature range -40~+85℃, 1.5KVDC I/P-O/P isolation voltage, compliance with EN501 55 railway standard, continuous-mode short circuit protection, etc. What's more, the models account for different input voltage 9~36V and 18~75V 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 long lifetime, high reliability, and excellent quality, Meanwell RDDW08G 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.
