The present disclosure relates to a communication system for serial communication. The communication system may include a master communication device; and at least one slave communication device comprising a unique identifier, wherein the master communication device is connected to the at least one slave communication device via a signal line configured for communications, wherein the master communication device is configured to read at least a part of the unique identifier via the signal line, and assign an address to the at least one slave communication device based at least in part on the unique identifier, and transmit the address to the at least one slave communication device via the signal line.

Communication system for serial communication between communication devices

The present disclosure relates to an uninterruptable power supply for an electrical consumer. The uninterruptable power supply may include a first current path; a second current path, where the first current path and the second current path are configured to supply electrical energy; a first switch configured to interrupt the first current path; a voltage transformer configured to limit a current intensity of an electrical current, where the voltage transformer is in the second current path; and a controller configured to open the first switch when a current intensity limit value of the electrical current in the first current path is reached to electrically interrupt the first current path and conduct the electrical current over the voltage transformer to limit the current.

Uninterruptible power supply

A protective arrangement for protecting an electrical device against an overload current includes: an input at which a current is supplied to the protective arrangement by a power supply; an output via which the current (I) is transferred in the form of an output current to the electrical device; a safety switch in a power line between the input and the output, which safety switch disconnects the power line when a set tripping current is exceeded; and a current sensor which measures the current () in the power line when the electrical device is connected, the current sensor being able to set the tripping current, on the basis of the measured current (), to a value that is greater than the measured current () by a specified difference (&#x394;).
