System Description
-48V DC @ up to 4000 Amperes Power System
The NetSure™ 721
NPBB
DC Power System is a complete integrated
power system containing -48V DC rectifiers or converters, optional
+24V DC converters, intelligent control, metering, monitoring,
and distribution.
This power system is designed to power a load while charging a
positive grounded battery. This power system is capable of
operating in a batteryless installation or off battery for
maintenance purposes. The power system is designed for
operation with the positive output grounded.
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 or shipping brackets 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
+24V 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 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 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
Instructions (UM1M820BNA or UM1M820DNA400) for more
information.
