Eltek Flatpack2 DC/DC 18-75V 24V 48V 1350W (Part No.:241115.600 241115.602)
The Flatpack2 DC/DC converters add new flexibility to the Flatpack2 power systems. Secondary 24 Vdc or 48 Vdc outputs can be provided from the main voltage battery. Application requiring galvanic isolation between the loads can now also be addressed.
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.
