PURPOSE:To convert the power source voltage into the voltage corresponding to each load and also to decrease the capacity of a transformer by connecting the low voltage supply line to low voltage load with the high voltage supply line to high voltage load through a transformer. CONSTITUTION:In case of using a low power source 21, for example, in case of using a container on land, since the power source voltage is 200V, the main switch 22 for low voltage is turned on and the main switch 32 for high voltage is turned off. Then, each relay 23, 33, and 36 is turned on, whereupon the power source voltage of 200V is applied from the low voltage power source 21 to a compressor motor 24, and that compressor 24 rotates. |
