ACS880-1607 - DC-DC converters

For energy storage and reuse 

This converter can transfer energy from a common DC bus of a drive system into an external energy storage. From there it can transfer the energy back to the DC bus when needed. Energy storages can be batteries or super capacitors. Applications for energy storage and reuse are found in a range of industries, such as marine (heave and peak load compensation) and process industry (electrical braking or DC bus voltage stabilization). The converter unit consists of R8i and converter units.

Customer benefits include reduced costs (less fuel consumption, less or smaller generators in ships), improved ship performance and safety in critical situations.


  • Modular design
  • Compact converter units provides small footprint for assembly
  • Same R8i unit hardware as with R8i inverter module
  • Fast and accurate current control providing rapid response in dynamic situations
  • Process stability and energy savings in various applications
