Systems, North America, Inc. Any copying, use, or disclosure of it without the written permission of Emerson Network Power, Energy Systems, North America, Inc. is strictly prohibited.
This system consists of the following components.
Distribution Cabinet
The system always includes a minimum of one distribution cabinet, which provides
DC distribution through fuses and/or circuit breakers. The distribution cabinet is
factory mounted in the relay rack specified when ordered.
Four different sizes of distribution cabinets are available to accept from one (1) to
four (4) distribution panels. A variety of distribution panels are available that provide
load distribution, battery distribution, and dual voltage load distribution for use with
-48V converters. These distribution panels are configured to accept either bullet
nose type circuit breakers and TPS/TLS fuseholders, TPH fuses, TPL-B fuses, or
GJ/218 circuit breakers.
The distribution cabinet may be equipped with low voltage load disconnect (LVLD),
low voltage battery disconnect (LVBD), and manual battery disconnect.
ACU+ (Advanced Control Unit Plus) Controller
The system contains one controller. The controller provides power system control
(including optional low voltage battery disconnect (LVBD) and low voltage load
disconnect (LVLD) control), rectifier control (including a charge control function),
converter control, metering functions, monitoring functions, and local/remote alarm
functions. The controller also supports rectifier temperature compensation if the
system is equipped with a temperature probe(s). Temperature probe(s) may also be
designated to monitor ambient air temperature and/or battery temperature. The
controller also provides data acquisition, system alarm management, and advanced
battery and energy management. The controller contains an LCD display and
keypad for local access. The controller provides Ethernet connection and supports
software upgrade via its USB port. It also comes with a comprehensive web page
and SNMP capability for remote system management. Refer to the ACU+ Controller
User Instructions (UM1M820BNA) for more information.
Module Mounting Assembly
The system contains one module mounting assembly which houses rectifier modules
and optional DC-DC converter modules. A module mounting assembly consists of
one (1) to four (4) 8-position module mounting shelves. Refer to Power Data Sheet
PD588705200 (PD588705201, PD588705202, PD588705203, PD588705204) for
more information.
Rectifier Modules
The system contains rectifier modules, which provide load power, battery float
current, and battery recharge current during normal operating conditions. Refer to
the Rectifier User Instructions (UM1R243000) for more information.
Optional DC-DC Converter Modules
Where –48VDC load power is also required, DC-DC converter modules are available.
Refer to the Converter User Instructions (UM1C24481500) for more information.
