Abstract
A power supply control circuit, which is connected to a stabilized direct current power supply having a pair of first and second output terminals and a pair of first and second remote sensing terminals, includes: a current detector configured to detect an output current that is supplied to a load from the stabilized direct current power supply, and to output a current detection voltage; a current difference output unit configured to output a current difference voltage corresponding to a voltage difference between the current detection voltage and a current setting voltage; and a control voltage generator configured to generate a control voltage and output the control voltage to the first remote sensing terminal so as to perform a constant current control operation. The current detector, the current difference output unit and the control voltage generator are operated by only the direct current voltage supplied by the auxiliary power supply.
