DC power supply / fanless / railway approval
DC converters
Primary clocked DC converter modules are used, among other things, to generate different (consumer) voltage levels from central DC voltages, also battery-supported.

Scope of application
Primary clocked DC converter modules are used, among other things, to generate different (consumer) voltage levels from central DC voltages, also battery-supported.
Our clocked DC converter modules for use in the low-voltage range can be connected in parallel in any quantity to increase power and redundancy.
The units are designed as plug-in modules for cabinet installation and offer galvanic isolation between input and output.
The connections on the front make it easy to replace the modules. On request, we offer special DC converters without galvanic isolation for adapting specific battery voltage ranges to specified consumer voltages, for example (function: e.g. “step-up converter”).
Due to their design, our modules are ideally suited for a wide range of industrial applications.
Essential features
- Galvanic isolation between input and output
- High efficiencies
- Parallel switchable without additional control unit
- Compact design with easily accessible connections on the front side
- Fanless design (low noise, no fan replacement necessary)
- High test voltages acc. EN 50124-1 from the railroad sector
Module-specific:- Integrated decoupling diode
- 2 x IN Short-circuit current, limited to 1.2 to 1.5 s
- Relay interface with potential-free changeover contact (operation / fault)
- Signalling by means of LEDs, partly digital voltmeter
