ABSTRACT:
A digital controller used in regulating the output of a power supply including a diagnostic circuit for sensing the failure of a component in the power supply. Upon the occurrence of a fault, signals are generated locating the component which caused the shutdown of the power supply. The fault signals are inputted into a plurality of encoders which determine the priority between two or more simultaneous occurring faults and which further outputs binary signals identifying the faulty component. The binary signals are then latched and displayed in a LED display which may be actuated any time after the fault has occurred by the operation of a switch member.
