ACS880-1607 DC-DC converters
DC/DC converter transfers energy from a common DC bus of a multidrive into an external energy storage. From there it can transfer the energy back to the DC bus when needed.
For energy storage and reuse
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.
Technical data
ACS880 multidrives offer a wide selection of pre-defined options, which include the typical requirements of different industries. ACS880 multidrives provide flexibility to ensure that even the larger drive can be be modified to meet space requirements/ to fit to available space on installation site.
