Classification: CPC H  G | IPC G  H

Claim 0:
1. A terminal protection voltage detector circuit for protecting a terminal block having a plurality of output terminals in a power supply apparatus, the terminal protection voltage detector circuit comprising:
a current detector configured to detect a plurality of output currents flowing from the power supply apparatus to a plurality of loads via a plurality of output terminals,
a first comparator configured to compare a sum of the plurality of detected output currents with a predetermined first threshold, and output a first comparison result signal when the sum of the plurality of output currents is larger than or equal to the first threshold,
a second comparator configured to compare a maximum value of the plurality of detected output currents with a predetermined second threshold, and output a second comparison result signal when the maximum value is equal to or larger than the second threshold; and
a current stop circuit configured to stop a current from flowing from the power supply apparatus to the plurality of output terminals based on the first comparison result signal or the second comparison result signal.
