Inverter for traction motor and generator up to 510 kW continuous and up to 760 kW peak electrical power (500 V and cosφ 0.Further design benefit is the ability to use one hardware for thre different purposes. When these reliability benefits are combined with high power density, support for all common motor types, 99% efficiency and flexible CAN bus interface you get a product perfectly tuned for heavy working machines usign electric power trains.
HES880 design does not have any fans, batteries or electrolytic condensators, so it is maintenance free. The of the design covers the benefits mentioned above but it is much more. Mining operation itself is also very demanding so we designed HES880 to withstand heavy vibration and shocks and to be able to handle strong cyclic loads, all of which are normal for heavy machinery operation. When we add to this the high cooling liquid temperature, we get a drive that can be used in very harsh environments. Ability to meet all requirements of the operationĪs mining is performed in a very wide range of atmospheres we have designed our HES880 Mobile Drive to tolerate a wide range of ambient temperatures and to have a high environmental protection class.Capability to withstand the operating environment.Product reliability can be divided into three parts. DC/DC converter for super capacitor or battery interface, up to 620 kW.Bi-directional line converter for grid connectivity.Inverter for traction motor and generator up to 510 kW continuous and up to 760 kW peak electrical power (500 V and cosφ 0.98).Having spare parts onboard is easy as there is only one hardware that can perform in three different modes. High fault current is needed for the electric protections to pick up faults. The File System Driver stores a list of up to five user credentials for accessing one or more Harmonic. While the grid quality and ability to compensate harmonics are obvious benefits, the high fault current capability is just as important. You can ingest, playout, archive, edit, transcode and control over-the-top (OTT) adaptive bitrate streaming in one place. The key design features of our off-grid functionality are high quality of the electric power in the grid, capability to feed high fault currents and ability to compensate harmonics. Harmonic MediaGrid® is perfect for digital media applications requiring shared, real-time storage. Thanks to the very compact size and IP67 cast aluminum enclosure HES880 is very well suited especially for smaller vessels where drives need to be installed in tight spaces with limited/no protection from the elements. HES880 is suitable for many shipboard applications like propulsion, generators, DC/DC conversion (energy to and from batteries and super capacitors), cranes, and winches.
