    摘要: An electronic apparatus includes a power supply portion, a plurality of loads, a drive portion, and a restriction processing portion. The plurality of loads are driven by power output from the power supply portion. The drive portion is provided corresponding to each of the loads and performs a state transition between a drive state in which the load is driven and a non-drive state in which the load is not driven. When stoppage of power supply from the commercial power supply to the power supply portion continues beyond a reference time while a plurality of drive portions are in the drive state, the restriction processing portion can restrict activation of some or all of a plurality of loads whose operations have been stopped by the stoppage of the power supply from the commercial power supply in response to resumption of the power supply from the commercial power supply.

    摘要: A boat protection system comprises a hub system and at least one auxiliary module. The hub system comprises a hub housing defining at least one hub guide portion, at least one hub electrical connector supported by the hub housing, and a DC bus operatively connected to the at least one hub electrical connector. The at least one auxiliary module comprises an auxiliary housing defining at least one auxiliary guide portion, at least one auxiliary electrical connector supported by the auxiliary housing, and at least one functional component. At least one hub guide portion engages at least one auxiliary guide portion to support at least auxiliary housing relative to the hub housing such that at least one hub electrical connector engages at least one auxiliary electrical connector. The at least one functional component of the at least one auxiliary module is operatively connected to the DC bus.

    摘要: A back-up power supply system (1) is configured to supply electric power from an electric storage device (5) to loads (3) when a power supply (2) is defective. The back-up power supply system (1) includes a first voltage conversion circuit (6) configured to convert an output voltage of the electric storage device (5). The loads (3) include a first load (31) and a second load (32). The back-up power supply system (1) is configured to supply power from the electric storage device (5) to the first load (31) not via the voltage conversion circuit (6), and to supply electric power from the electric storage device (5) to the second load (32) via the voltage conversion circuit (6).

    摘要: A method and apparatus for controlling the total load presented to an AC power source such as a generator or inverter used to provide backup or portable power. The frequency of the output AC power is controlled in response to the loading on the power source, thereby providing information about that loading of the power source which is carried by the AC power itself, thus reducing or eliminating the need for traditional wired and wireless communications. By controlling the frequency of AC power, controllable loads and load control devices can determine the amount of remaining power available from the power source in order to determine if a given load can be connected without creating an overload. The frequency may also be controlled at the power source to indicate an overload, with the loads being responsive to that overload frequency to reduce the load and thereby alleviate the overload.

    摘要: A system can include a field device and a power limited source operatively connected to the field device and configured to supply a main power to the field device up to a power limit threshold. The system can include a bulk energy storage assembly operatively connected to the field device. The bulk energy storage assembly can be configured to provide a supplemental power to the field device when either the main power drops below a demand power from the field device, or when the demand power from the field device exceeds the power limit threshold.
