Compact and powerful on-board power supply
for urban transport vehicles
The BNU 600 series represents the 6th generation of the KIEPE´s auxiliary power supply which has been continuously improved for over 35 years. These power converters use cost-effective and service proven IGBT technology. Thanks to a patented circuit design in combination with modern control technology, a power density and efficiency is achieved, which is comparable to silicon carbide auxiliary power systems currently available on the market for railway applications.
The modular design featuring reduced module dimensions and high efficiency makes the BNU 600 especially attractive for retrofit projects. The complete device or individual inverter modules can be upgraded to the BNU 600 series.
