New 500-Watt Railway DC to DC Converters


MEAN WELL’s new 500-Watt railway DC to DC converter will be arriving into ADM’s warehouse in October 2020. 

The new RSD-500 series DC to DC converters have been tested and certified to railway standard EN50155, as well as the telecommunications electrical safety standard AS/NZS62368 and EMC standard EN55032. 

This means that these new DC to DC convertors are suitable for use on locomotives, rolling stock, and passenger cars, as well as numerous other automotive & industrial applications, where resistance to vibration and shock is required. 

The commonly used railway input voltages of 24VDC, 36VDC, 48VDC, 72VDC, 96VDC, and 110VDC are accommodated within the range of RSD-500 models.  

There are three output voltages available: 12VDC, 24VDC, and 48VDC all of which can be adjusted up to 15% above the rated output voltage. This is particularly useful for combatting voltage drop over longer runs of cable.  

Input Voltage Range

12VDC Model

24VDC Model

48VDC Model

16.8 ~ 33.6 VDC




33.6 ~ 67.2 VDC




67.2 ~ 154 VDC





With 4000VDC I/O reinforced isolation, the RSD-500 series DC to DC converters are the ideal solution for additional system isolation in DC UPS and battery voltage regulator applications. 

All models have a wide operating temperature, with no derating below 55°C and are backed by a manufacturer’s 3-year warranty.  

Please contact ADM on 1300 236 467 for further information.
