MAC - Choose The Right Backup Power Supply

The Institute of Electrical and Electronics Engineers (IEEE) recognizes three categories of backup power supplies: off-line, line-interactive, and on-line. During a power source interruption, an off-line BPS disconnects the equipment from the power source, a line-interactive BPS shares the load between the power source and the battery, and an online BPS forces the equipment to operate exclusively on battery power.
