Abstract: PROBLEM TO BE SOLVED: To easily change the output voltage of a power unit even when such a command signal that corresponds to the output voltage is not continuously supplied to the unit, by outputting a different output voltage to the outside based on the monitored result of a terminal state monitoring section. SOLUTION: A state selecting circuit 3 always monitors the disconnecting and short-circuiting states between external terminals High and Com and between external terminals Low and Com, and sends its monitored results to an output setting section 6 by assuming each state of a 'Normal' state in which the output voltage V0 of a variable power unit is set at a rated voltage, 'High' in which the voltage V0 is set at a higher limit voltage, and 'Low' in which the voltage V0 is set at a lower limit voltage. The output setting section 6 stores setting voltage values in advance and, upon receiving the monitor signal from the selecting circuit 3, outputs one of the setting voltage values to a D/A-converting section 7 as a digital signal.  The section 7 sends an analog command signal to the terminal PV of a main power unit circuit 2 and the output voltage V0 corresponding to the command signal is supplied to a load through output terminals +V and -V.
