PURPOSE:To enhance reliability of appliance by making possible to supply an electronic module with power in accordance with power consumption thereof thereby protecting the electronic module against breakdown even upon occurrent of abnormality therein and stabilizing power supply thereto. CONSTITUTION:The power supply system comprises a feedback resistor Rp producing a feedback current proportional to a power supply voltage for an electronic module, detecting resistors Rs1, Rs2 producing a rated current proportional to the load conditions of the electronic module from thus produced feedback current, and means for comparing thus produced rated current with the feedback current produced from the feedback resistor Rp. |
