相回転検出回路。Two sets of photocouplers are connected to the three-phase AC power supply whose phase rotation is to be detected to obtain a pulse-like three-phase signal, and the three-phase signal which is the output of one of the above photocouplers is input as data, and the other is output. A phase rotation detection circuit comprising: a D flip-flop which receives a three-phase signal as a clock input; and a display circuit that is controlled by the output of the D flip-flop and displays whether the phase rotation is correct or incorrect.
