A three-stage charging system designed to prolong the service life of IBM
UPS batteries. By charging the batteries only when necessary, battery life is
significantly improved. Charging stage one: quickly recharges battery to
approximately 90% of capacity. Charging stage two: fully charges the
battery to 100%. Charging stage three: rest mode prevents overcharging.
Charging stage one is initiated after a power outage or periodic UPS
self-test.
Time during which the load can be supplied by the UPS operating on
battery power.
Internal UPS test to check battery status.
The devices connected to the UPS can be started even if AC input power is
not available. The UPS operates on battery power alone.
Battery discharge beyond the permissible limit, resulting in irreversible
damage to the battery.
Devices or equipment connected to the UPS output.
A battery level indicating that battery power is low and that action should
be taken to prevent the imminent disruption of power to the load.
The AC-power line supplying the UPS under normal conditions.
Ratio of the power effectively drawn by the load to the maximum output
of the UPS.
It is possible to modify certain UPS parameters set in the factory. Certain
UPS functions can also be modified by the software to better suit user
needs.
Controllable outlets for automatic load shedding, remote shutdown and
sequential restart (personalized using software).
Uninterruptible Power System.
This function enables or disables initiation of UPS ON/OFF control
sequences by computer power-management software.
