A high-efficiency, scalable 1U rack-mounted charger that supports the operation of electric mobility.
In the operation of electric mobility within the public transportation industry, a stable charging environment is required to maintain vehicle uptime, along with the construction of efficient systems in limited installation spaces. Particularly, to support long-duration operations, the reliability of chargers and flexible scalability to accommodate future vehicle expansions are essential. A design that minimizes the impact on the entire system in the event of trouble supports stable operation management. The DBR Series is a high-density charging solution that addresses these challenges. 【Usage Scenarios】 - Charging facilities at electric bus and small mobility vehicle depots - Construction of charging systems in limited spaces - Sites requiring power expansion in anticipation of future vehicle additions 【Benefits of Implementation】 - The 1U slim design allows for effective use of installation space - Flexible output expansion through parallel connections enables system construction according to the number of vehicles - Built-in OR-ing FET maintains operation of the entire system even in the event of trouble with some units
