An elevator or lift UPS falls under the category of offline UPS and consists of three main parts which are a charger, batteries and an inverter. A lift UPS takes three-phase supply and powers the elevator while charging the batteries at the same time. This electronic device can be better described as an effective power backup solution for elevators.

An elevator UPS is manufactured by taking several important factors into consideration such as the duration of a common power cut, capacity of the lift motor, type of elevator, whether it would be used in a residential or commercial area, etc.
