UNINTERRUPTIBLE POWER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an uninterruptible power system capable of adjusting the cooling capacity on a heat generation source.SOLUTION: A housing 100 storing an uninterruptible power module is provided with a cooling fan 17 for cooling inside the housing 100. The housing 100 is formed with an opening 120. The opening 120 formed in the housing 100 and an opening 120 which is formed in a housing 100 of an abutting uninterruptible power module 1 are arranged to face each other. The uninterruptible power system further includes a fan control circuit for controlling a cooling fan 17. The fan control circuit controls the cooling fan 17 to start and stop operation based on the total load amount of the plural uninterruptible power module.SELECTED DRAWING: Figure 5
