AI Technical Summary

Problems solved by technology

Uninterruptible power supply units are used concomitantly with commercial power sources in the various load facilities such as OA equipment, medical equipment, power distribution equipment for the medical field, amusement facilities, electric power supply facilities to buildings.

In case of purchasing UPS, the initial investment is required to be large, and in case of introducing UPS with lease or rental contract, there are such disadvantages that the rental fee may be high and that USP may not be provided for the long-term service lasting for 10 or 15 years.

In case that the user purchases UPS, the user has to provide the initial investment and bear heavy duty on large amount of investment.

In the lease or rental contract of UPS, though the client is not required to provide the initial investment, the annual expenditure may become comparatively higher than the case of purchasing UPS, and there is such a disadvantage that USP may not be provided for the long-term service lasting for 10 or 15 years.
