For providing a reliable voltage adjusting apparatus in low cost, a low-voltage control apparatus controls a high-voltage power supply circuit to be switched power off by transmitting a power-off signal through a second communication line arranged between the high-voltage power supply circuit and itself through an isolation unit when an information signal from an equalizing apparatus is not transmitted within a predetermined first malfunction judging period.
