This Flatpack2 DC/DC converter provides a secondary 310-400 Vdc output from a main 48V or 60V battery bank. This allows for high efficient transmission of battery backed up energy to small remote sites without grid.
The galvanic isolated CAN bus can be connected to a supplying Eltek power system’s control system allowing monitor and control of the DC/DC converters without adding a separate controller.
