Since the constant voltage amplifier tends to achieve zero output impedance and alters the output current whenever the load resistance changes, while the constant current amplifier causes the output impedance to be infinite and changes the output voltage in response to any load resistance change, it is obvious that the two amplifiers can not operate simultaneously. For any given value of load resistance, the power supply must act either as a constant voltage source or as a constant current source - it can not be both transfer between these two modes is accomplished at a value of load resistance equal to the ratio of the output voltage control setting to the output current control setting Earth-Referenced Logic Front PanelChapter 4 Theory of Operation Earth-Referenced Logic Service Service Operating Checklist Is the Power Supply Inoperative?Does the Power Supply Fail Self-Test?
