RSDW20UW & RDDW20UW DC-DC Converters

MEAN WELL RSDW20UW and RDDW20UW DC-DC Converters are 20W output module DC-DC railway converters. The series features an 18:1 (8.5V_DC to 160V_DC) ultra-wide voltage input and various output voltages of 5V/12V/15V for single output and ±12/±15V/±24V for dual outputs. These reliable converters offer up to 89% high efficiency, a 3KV_AC I/P-O/P isolation voltage, and a wide working temperature range of -40°C to +95°C. MEAN WELL RSDW20UW and RDDW20UW DC-DC Converters are certified to UL62368-1, EAC TP TC004, and railway EN50155. The series is ideal for railways, trams, MRT, buses, and other transportation applications.
