CIRCUIT FOR CONTROLLING POWER SOURCE OF MONITOR

摘要

PURPOSE: A circuit for controlling power source of a monitor is provided to automatically restore a system from an erroneous operation generated by imbalance of power source. CONSTITUTION: A power source adapter(20) converts AC(Alternating Current) power source to DC(Direct Current) power source and voltage usable inside a system. An electric potential detecting part(21) detects electric potential of DC voltage output from the power source adapter. A device(22) is operated by the power sources output from the power source adapter. A control element(23) senses change in electric potential of the device from an electric potential signal output from the electric potential detecting part, so that the control element resets an inner set value of the device.
