The above illustrations show power flow during the battery backup mode.
When commercial ac power failures occur, the UPS's batteries instantly begin
supplying dc voltage to the UPS's main inverter circuit. This circuit changes
(inverts) the dc power into ac power. The ac power is available at the unit's
output receptacles. This back-up process will continue until the UPS's battery
voltage drops below a specific minimum level. When this occurs, the batteries
will stop supplying power to the load. This minimum level is the rated minimum
voltage (Vmin). The rated battery voltage chart on page 5-6 (See Section 5.4
for battery backup time) shows (Vmin).
