HES880 is suitable for many shipboard applications like propulsion, generators, DC/DC conversion (energy to and from batteries and super capacitors), cranes, and winches. 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.
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. While the grid quality and ability to compensate harmonics are obvious benefits, the high fault current capability is just as important. High fault current is needed for the electric protections to pick up faults.
Also beneficial is the possibility to use dual winding control when high power or redundancy is needed. In high power application you stil have half power available if one unit fails.
Having spare parts onboard is easy as there is only one hardware that can perform in three different modes.
- Inverter for traction motor and generator up to 510 kW continuous and up to 760 kW peak electrical power (500 V and cosφ 0.99)
- Bi-directional line converter for grid connectivity
- DC/DC converter for super capacitor or battery interface, up to 620 kW
