To enable a disk array device to operate keeping a redundant function with a simple configuration.SOLUTION: A disk array device comprises a first controller and a second controller that is connected to the first controller through a power supply path, and that has the same circuit configuration as the first controller. The first controller and the second controller each include: a first element connected between a voltage converter and a load device; a second element connected between the load device and a resistor; the resistor, one end of which is connected to the power supply path, and the other end of which is connected to the second element; a control unit that controls a connection mode or shutoff mode of the first element by outputting a first control signal, and that controls a connection mode or shutoff mode of the second element by outputting a second control signal; and a second control signal supply path connected between the other end of the resistor and an output part of the second control signal of the control unit.SELECTED DRAWING: Figure 3 【課題】シンプルな構成で冗長機能を保ったまま稼働することを可能とする。【解決手段】第１コントローラーと、前記第１コントローラーと電源供給経路により接続される、前記第１コントローラーと同一の回路構成を有する第２コントローラーとから構成され、前記第１コントローラーおよび前記第２コントローラーは、電圧変換回路と負荷デバイスとの間に接続された第１素子と、前記負荷デバイスと抵抗器との間に接続された第２素子と、一端が前記電源供給経路に接続され、他端が前記第２素子に接続された前記抵抗器と、前記第１素子の接続モードまたは遮断モードを、第１制御信号を出力して制御し、前記第２素子の接続モードまたは遮断モードを、第２制御信号を出力して制御する制御部と、前記抵抗器の他端と前記制御部の前記第２制御信号の出力部との間に接続された第２制御信号供給経路とを有する。【選択図】図３
