Description
RSDW08 and RDDW08 series are 8W module type DC-DC reliable railway converter with DIP24 package. It
features international standard pins, a high efficiency up to 86%, wide working temperature range
-40~+85
℃
, 1.5KVDC I/P-O/P isolation voltage, compliance with EN50155 railway standard, continuous-
mode short circuit protection, etc. 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, which are 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.

NOTE
1.All parameters are specified at normal input(F:24Vdc, G:48Vdc), rated load, 25
℃

μ
f capacitor.
3.Line regulation is measured from low line to high line at rated load.
4.Load regulation is measured from 10% to 100% rated load.
5.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please
refer to EMI testing of component power supplies.(as available on http://www.meanwell.com)
