Lucent Technologies ECS Minicell Battery Plant H569-420
Issue 5 February 1997
Product Description 2 - 5
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, monitor and
diagnostic functions required to administer the battery plant.
Batteries: provide energy storage for an uninterrupted power
feed to the using equipment during loss of ac input or rectifier
failure.
DC Distribution: provides overcurrent protection, connection
points for the using equipment, and bus bars used to interconnect
the rectifiers, batteries, plant shunt, and dc distribution.
Converters: transform 24-volt source voltages into regulated,
low noise -45.6 to -50.4 volt dc power sources for use with
telecommunications loads.
