• Controller
The controller controls the operation of the rectifier modules. The controller also provides
power system control, metering, monitoring, and alarm functions.
NCU (NetSure Control Unit): 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), metering functions,
monitoring functions, local/remote alarm functions, and connections for binary inputs and
programmable relay outputs. 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 a color TFT
display and keypad for local access. The controller provides an Ethernet port and comes
with comprehensive webpages for remote access. The controller has SNMP V3
capability for remote system management. The controller supports software upgrade via
its USB port. Refer to the NCU Controller Instructions (UM1M830BNA) for more
information.
ACU+ (Advanced Control Unit Plus): 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), 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 an Ethernet port
and comes with comprehensive webpages for remote access. The controller has SNMP
capability for remote system management. The controller supports software upgrade via
its USB port. Refer to the ACU+ Controller Instructions (UM1M820BNA) for more
information.
SCU+ (Standard Control Unit Plus): The SCU+ provides Rectifier Module and optional
Low Voltage Battery Disconnect (LVBD) or Low Voltage Load Disconnect (LVLD) control,
metering functions, monitoring functions, and local/remote alarms. The SCU+ contains
an LCD display and keypad for local access. It provides connection for binary inputs,
programmable relay outputs, and a charge control function. The controller also supports
rectifier temperature compensation if the system is equipped with a temperature probe
(or multiple temperature probes connected via a Temperature Concentrator (SM
TEMP),
and ambient temperature monitoring if equipped with a second temperature probe. The
SCU+ also provides Ethernet connection and SNMP capability.
• Distribution Unit
Various Distribution Unit options are available, as described in this document. The
Distribution Unit can be equipped with an optional Low Voltage Battery Disconnect
(LVBD) or Low Voltage Load Disconnect (LVLD) contactor.
