Summary:PROBLEM TO BE SOLVED: To minimize increment in the output capacity of power supply and to attain redundancy without increasing the number of power supplies by branching a power supply output to two outputs, connecting one of the outputs in parallel with the other through a diode and then connecting one output to a load sequence. SOLUTION: An output from a power supply 1 is branched to two outputs, one is directly connected to a load sequence 10 and the other is connected to a diode 8. An output 6 from a power supply 2 is branched to two outputs, one is directly connected to a load sequence 12 and the other is connected to a diode 9. The outputs of the diodes 8, 9 are connected in parallel and connected to a load sequence 11. Electronic parts loading units 20 to 23 and fans 30 to 33, 40, 50 to 53 are loaded in cooling air routes 60 to 63 and the device is redundantly constituted so as to cool the units 20 to 23 even when any one of the FANs 30 to 33 is stopped. Even when a fault is generated in the power supply 1 and the output 5 is stopped for instance, power is normally supplied to the load sequence 11 and the FAN 40 is normally driven.
