In an on-line UPS, the batteries are generally connected to the inverter, to ensure no power transfer switches are necessary. When power decline occurs, the rectifier merely drops out from the circuit and the batteries retain the power constant and unchanged.

Your eyes aren't deceiving you: the on-battery AC output from this specific UPS is cleaner than my wall power! This UPS will run any electronic machine within just its load boundaries, since its on-battery output is as close to great wall power as can make no useful distinction.
