AC Input: connects the commercial and/or standby ac power sources to the rectifiers within the system
and provides overcurrent protection. In some applications the ac service is wired directly to the rectifiers
and overcurrent protection is provided at the service panel.
Rectifiers: convert an ac source voltage into the dc voltage level required to charge and float the batteries
and to power the using equipment.
Controller: provides the local and remote control, monitoring, and diagnostic functions required to
administer the power system.
Batteries: provide energy storage for an uninterrupted power feed to the using equipment during loss of
ac input or rectifier failure.
DC Distribution Panel: provides overcurrent protection, connection points for the using equipment, and
bus bars used to interconnect the rectifiers, batteries, and dc distribution.
Battery Connection Panel: provides connection points for the battery strings through battery disconnect
fuses or contactors and current monitoring shunts.
