PURPOSE:To recover normal parallel operation quickly by resetting an abnormal power supply detecting circuit only upon first detection of abnormal current after execution of a power throw-in command thereby providing a parallel operation command again. CONSTITUTION:A control section l receives abnormal voltage signals 46.1-46.N and abnormal current signals 45.1-45.N from various power supplies. When an abnormal voltage is detected based on an abnormal voltage signal, disconnection of stabilized output is commanded by a throw-in/disconnection signal 43. Only when an abnormal current occurs in one of a plurality of power supplies for the first time after the control section commanded throw-in of stabilized power, the control section 1 provides a reset signal 44 to each power supply. The reset signal 44 is not provided for second and following occurrence of abnormal current after the control section 1 commanded throw-in of stabilized power. |
