Abstract: A power distribution unit is disclosed. The power distribution unit comprises a plurality of input assemblies respectively connected to a plurality of power sources for inputting power, a plurality of output assemblies for outputting processed power, a power distributing module for transmitting the power, and a power switch module. The power switch module switches to connect with one of the input assemblies to conduct the power source connected to the input assembly with the connected output assembly (s), and switches to connect with another input assembly to conduct another power source connected to the input assembly with the connected output assembly (s) when determining that a switching condition is satisfied. The present disclosed example can effectively save the space of arranging the power switcher, and enhance convenience of installation via integrating the power switch module into the power distribution unit.

Abstract: A power redundant system includes a switch module, a power-supplying module and a control unit. The switch module includes switch units. Each switch unit switches a power as an input power. The power-supplying module includes power-supplying units. Each power-supplying unit is connected to a switch unit correspondingly and converts the input power into an output power and supplies the output power to a load. The control unit controls the switch units to switch one of input sources of the power as the input power. If one of the switch units or power-supplying units is not operational, an electric power supplied by the power-supplying units connected to the remaining switch units correspondingly is greater than or equal to an electric power required by the load. When one of the input sources is abnormal, the control unit controls the switch units to switch to another input source.

Abstract: This disclosure is directed to a flameproof electronic device having a housing, an electronic assembly, and a thermal-expandable structure. The housing has a pair of vents. The electronic assembly is accommodated in the housing, at least a part of the electronic assembly is spaced from the housing to enclose a flow channel between the electronic component and an internal surface of the housing, and the flow channel communicates with the vent. The thermal-expandable structure covers the internal surface of the housing or an external surface of the electronic assembly. The heat-expandable structure expands to block the flow channel when being heated to greater than or equal to a predetermined temperature.

Abstract: A dual-input power switching system includes a first DC power source, a second DC power source, a DC conversion circuit, and a boost-up circuit. The first DC power source provides a first DC voltage, and the second DC power source provides a second DC voltage. The DC conversion circuit receives the first DC voltage or the second DC voltage being an input voltage, and converts the input voltage to supply power to a load. The boost-up circuit provides a hold-up voltage to boost up the input voltage when the first DC power source stops supplying power to lead to power drop of the input voltage, such that the input voltage reaches to a specific voltage that is greater than the second DC voltage and afterward naturally decreases to be less than or equal to the second DC voltage.

Abstract: A power distribution apparatus with a backup energy-storing function receives a first input power source, and the apparatus includes an output module, a conversion module, an energy storage unit, and a management unit. When the first input power source is normal, the output module outputs the first input power source. Also, the management unit controls the conversion module to convert the first input power source to a first power source for charging the energy storage unit. When the first input power source is abnormal, the energy storage unit outputs a second power source to the conversion module. Also, the management unit controls the conversion module to convert the second power source into a second input power source for outputting the second input power source from a second output module.

Abstract: A power distribution system capable of network-connecting relay is provided. Power distribution units of the power distribution system execute a master-node-arbitrating process to generate an arbitration result, and respectively switch to a master node mode for being a master node or a slave node mode for being a slave node according to the arbitration result. When being the master node, a power distribution unit receives a monitor command from a remote management device via an external network, and transfers it to the corresponded slave node(s). When being the slave node, a power distribution unit executes the monitor command received from the master node. Therefore, the complexity of building system and the cost of building system can be effectively reduced, and network-connecting relay service can be provided.
