Safety power disconnection for remote power distribution in power distribution systems is disclosed. The power distribution system includes one or more power distribution circuits each configured to remotely distribute power from a power source over current carrying power conductors to remote units to provide power for remote unit operations. A remote unit is configured to decouple power from the power conductors thereby disconnecting the load of the remote unit from the power distribution system. A current measurement circuit in the power distribution system measures current flowing on the power conductors and provides a current measurement to the controller circuit. The controller circuit is configured to disconnect the power source from the power conductors for safety reasons in response to detecting a current from the power source in excess of a threshold current level indicating a load.

A method includes: providing a device having a counter that stores a cycle count measuring a number of clock cycles since the device was last turned ON or a timer that stores an elapsed time since the device was last turned ON; (a) flagging a first or additional defined memory location when the cycle count or the elapsed time reaches a first or additional first milestone; (b) unflagging the first or additional defined memory location when the cycle count or the elapsed time reaches a second or additional second milestone, wherein the second or additional second milestone is greater than the first or additional first milestone; (c) determining that the device is turned OFF and then ON again; repeating steps (a) through (c) a specified number of times; and resetting the device or turning a program ON when all the first or additional memory locations reach a specified flag configuration.

Systems for power distribution within a power source unit are well suited for use in power source units that work with power distribution networks such as may be found associated with wireless communication systems or the like. More specifically, exemplary aspects provide a flexible power cable that extends from a powering supply to printed circuit boards (PCBs) on which output power ports are located. The PCBs may be arranged in a cascaded or daisy chain topology or in a star topology relative to the powering supply.

The invention relates to a DC power distribution system (1), especially to an EMerge DC power distribution system, for distributing DC power. A power supply (5) supplies DC power to a track (2) to which an electrical load (9, 10) is attached. A communication device (11) is attached to the track (2), which a) wirelessly receives communication signals and transmits the received communication signals via a power line communication provided by the track to the power supply (5) and/or the electrical load (9,), and/or b) receives communication signals via the power line communication from the power supply (5) and/or the electrical load (9, 10) and wirelessly transmits the received communication signals. Thus, a communication setting is provided, which allows for a very simple integration of a control functionality for controlling, for instance, the power supply 10 and/or the electrical load by transmitting control signals via the communication device.

The first device, second device, and third device are connected so as to be bi-directionally communicable with each other over a first communication channel. The first device collects the measurement results of the second device and third device to monitor the power distribution system. The first device can stabilize the power distribution system by controlling the predetermined control device.
