DatasheetThe switched-mode DC-DC converter is designed for reliable conversion of DC voltages in technical systems, vehicles, control cabinets and industrial power supply applications. Depending on the version, different input voltages, output voltages and output currents are available. The series covers rated power levels from 60 to 240 W and is therefore suitable for a wide range of loads and supply concepts.
The devices operate as switching regulators and provide a stable output voltage in a compact housing. They are short-circuit protected and equipped with electronic overload protection. These versions do not provide galvanic isolation. Thanks to the simple mounting concept and practical electrical connections, the converters can be easily integrated into existing 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, depending on the selected version. Cooling is provided by convection or fan cooling, depending on the model. Versions with E1 approval are also available and are particularly suitable for mobile applications.
The DC-DC converters are a compact solution for supplying electronic modules, control units and electrical loads when a different stable DC voltage has to be generated from an existing DC power source.
