PROBLEM TO BE SOLVED: To provide a power control device for a vending machine capable of reducing electric energy consumed by the machine while keeping the performance of the vending machine. SOLUTION: This power control device has a function for detecting an input voltage and the range of the detection voltage is 100 V±20%. The detection voltage is set at 97 V. The voltage is outputted at a ratio of 95 V to 90 V when the input voltage is below 97 V, and the voltage is outputted at a ratio of 100 V to 90 V when it is above 97 V. An output circuit uses an auto transformer and is automatically changed over. COPYRIGHT: (C)2006,JPO&NCIPI
