Description

  Embodiments of the present invention relate to a control panel system such as a UPS system in which a plurality of uninterruptible power supplies (UPS) are combined.

  As a conventional UPS system, when installing a number of uninterruptible power supply units in which the UPS main body is housed in a bottomed cylindrical board container with an open ceiling, the backs of the boards face each other and A wiring space for performing the main circuit wiring between them is secured. In this case, a forced air cooling fan is installed in each panel container, and by rotating this fan, outside air is taken into the panel container from the air inlet formed in the lower side wall of the panel container. Is exhausted from the opening of the ceiling of the board container.

  As described above, outside air is taken into the board container and exhausted to the outside of the board container, so that the UPS main body as a heating element is cooled.
