PROBLEM TO BE SOLVED: To improve the cooling effect of an inverter, and to improve the maintainability of a control section, in a cabinet type water supply system having two or more inverters. SOLUTION: Two inverters are arranged in the ventilating direction of a heat sink with a ventilating passage arranged by a cover, and fans operated by being interlocked with the operation of the inverters are arranged in a cover section at both the ends of the inverters, so that when the inverters are operated, the ventilating direction is turned reversely. Thereby, the same cooling effect can be provided to either inverter. An inverter section is so arranged that a heat sink surface is located in parallel with a cabinet back surface, a gallery is arranged in a position where a cooling fan on the cabinet back surface is arranged, and a duct formed of a material having compressibility such as a rubber sponge is provided between the gallery and the fan, thereby a ventilating passage for cooling an inverter is formed. The control section is formed into a type which can draw out of a cabinet body, and further, a mechanism rotating the inverter section is provided, thereby maintainability is improved.
