Description: In the present day scenario of power shortage and sudden shutdowns, the Elevator UPS is essential at every place including offices, industries, malls etc. National Infotech’s ‘ARD’ is a customizable solution based on the STM32G0 microcontroller. It comes with a capacity of 1.5kVA and intelligently designed for fully automatic functioning of elevators in case of power failure. During normal functioning the elevator is directly connected to main power and only a small portion of the main supply is used for charging the storage batteries. In the event of a power failure, the elevator UPS automatically senses it and generates AC power from the batteries to run the elevator.
