conditioned AC power to a load. This is sometimes referred to as the "System".
UPS MODULE CABINET - The metal enclosure which contains the Converter / Charger,
Inverter, Static Transfer Switch, Internal Bypass line, operator controls, and internal control
systems required to provide specified AC power to a load.
UPS MODULE - The Converter / Charger and Inverter assemblies which, under the
direction of the internal control system and operator controls, provide specified AC power to
a load.
CONVERTER / CHARGER - The UPS components which contain the equipment and
controls necessary to convert input AC power to regulated DC power required for battery
charging and for supplying power to the Inverter.
INVERTER - The UPS components which contain the equipment and controls necessary to
convert DC power from the Converter / Charger, or the battery, to AC power required by
the critical load.
STATIC TRANSFER SWITCH - The device which connects the critical load to the bypass
line when the Inverter cannot supply continuous power.
BYPASS LINE - The line which conducts electricity directly from the input power source to the
critical load whenever the UPS is not completely operational.
AC INPUT POWER - Power provided by the electrical utility company, or auxiliary
