Systems and methods for the creation of a centrally controlled DC and AC power rail system within a structure. The rails utilize a centralized controller along with a plurality of distributed controllers to allow for power in the rails to be selectively distributed or not distributed to outlets attached to the rails. This allows for power to be distributed without the need for users to utilize hardwired switches, but to instead utilize generally wireless switch modules, which may be implemented in hardware and/or software to control the outlets. It also allows for devices designed to utilize DC power to be directly supplied with such power from the DC power rail without the need to include onboard AC-DC converters with each device.

An uninterruptible power supply device is basically a device that performs a full-time inverter feeding system using a first semiconductor switch, and when a second semiconductor switch, which is an optional item, is connected in parallel to the first semiconductor switch and a full-time bypass feeding system is selected, serves as a device that performs the full-time bypass feeding system using the second semiconductor switch. This leads to a low device cost compared with the case in which an uninterruptible power supply device employing the full-time inverter feeding system and an uninterruptible power supply device employing the full-time feeding system are designed and manufactured separately.

A power conditioner includes an inverter unit and a control unit that outputs an error signal indicating a mounting error of a first or second current sensor based on a result of detection by the first current sensor and a result of detection by the second current sensor.
