DatasheetThe switched-mode DC-DC converter is a compact voltage converter for converting DC voltages in industrial, mobile and electrical power supply systems. The series includes different versions with rated power from 60 to 240 W and is suitable for supplying control units, electronic modules, loads and auxiliary systems.
Depending on the type, input voltages of 24 V, 48 V or 60 V DC are available. The output voltages are 5 V, 12 V or 24 V DC. This allows different loads to be reliably supplied from an existing DC power source. The devices operate as switching regulators and provide a stable output voltage in a compact design.
The DC-DC converters are short-circuit protected and equipped with electronic overload protection. These versions do not provide galvanic isolation. Depending on the model, cooling is provided by convection or fan cooling. The electrical connection is made via flat connectors, M6 bolts or cable, depending on the type.
Thanks to their easy installation, robust construction and different voltage and power versions, the converters can be flexibly used in systems, vehicles, control cabinets and control applications. Versions with E1 approval are particularly suitable for mobile applications.
