Abstract
A load module for supplying a load may comprise an input terminal for coupling to a power supply and an output terminal for coupling to the load. A switching device may serve for the variable electrical coupling of the input terminal to the output terminal. A control unit coupled to the switching device may be designed to control an electrical coupling of the input terminal to the output terminal after the load module has been coupled to a power supply, via the switching device.

A load module for supplying a load, the load module comprising:
- an input terminal for coupling to a power supply;
- an output terminal for coupling to the load;
- a switching device for providing variable electrical coupling of the input terminal to the output terminal;
- and
- a control unit coupled to the switching device and configured to control an electrical coupling of the input terminal to the output terminal after the load module has been connected to the power supply via the switching device,
- wherein the control unit is further configured to allow a current flow, using a switched transistor, only in one direction.
A method for supplying power to a load module, comprising the steps of:
- measuring a current consumption across an input terminal coupled to a power supply;
- controlling a current across an output terminal based on the current consumption;
- determining a successful coupling of an input terminal of the load module to a power supply;
- and
- delaying electrical coupling of the input terminal to an output terminal of the load module, for coupling to a consumer, after measuring the successful coupling of the input terminal to the power supply.
