Railway standard acquisition product! A DC-DC converter ideal for applications in railways and transportation.
"48V Special Edition" Semi-sealed DC-DC converter "RSD Series" with excellent durability against moisture, dust, vibration, and heat.
It has obtained railway standards and has a wide input range, making it suitable for railways and all types of transportation systems. It is also adopted in onboard systems for railways, trams, special vehicles, emergency vehicles, as well as systems for robots and AGVs. Furthermore, in system design, since the external dimensions and weight do not change even when the voltage is altered, you can select it without any issues regarding installation location or mounting.
