(Distribution Only Bay) DC Power System is an integrated power system containing
rectifiers, intelligent control, metering, monitoring, and distribution.
This power system is designed to power a load while charging a positive grounded battery. The 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 power system can consist of the following components. The system must consist of one (1)
primary power/distribution bay or primary power only bay and may consist of up to seven (7)
additional bays. These additional bays may be a combination of secondary power/distribution bays,
secondary power only bays, and/or distribution only bays (maximum of 4 distribution only bays per
system). The system can be expanded right or left.
•
Power/Distribution Bays and Power Only Bays
Each power/distribution bay and power only bay can be equipped with up to ten (10) rectifiers.
The power/distribution bay and power only bay can be ordered factory configured for various AC
input options. The power/distribution bay also provides distribution. Distribution is divided into
two buses which accept a choice of fuse and circuit breaker types and sizes.
Each power/distribution bay and power only bay contains a monitor and control shelf. The
monitor and control shelf either contains an NCU controller (main bay) or NCU controller
interface (secondary bays), or an MCA (Meter-Control-Alarm) assembly and optional LMS
Monitoring System (main bay) or MCA interface (secondary bays). When equipped with an NCU,
an SM-DUE module is mounted in each secondary bay’s control shelf. Refer to “
” on page 2. An indicator is visible from the outside of the bay (at the top) which
illuminates if an alarm condition occurs.
When equipped with an NCU, the primary power/distribution bay or primary power only bay
contains a front panel touch screen PC connected to the NCU controller. The primary bay also
includes an NCU interface board (IB2) which provides digital inputs, temperature inputs, and relay
outputs for internal and external monitoring and alarms. An NCU extended interface board (EIB)
is also provided for additional inputs/outputs connections. Also furnished is the IB4 board which
provides a second Ethernet port. The Ethernet port located on the NCU controller’s front panel is
used to connect the front panel touch screen PC directly to the NCU. The Ethernet port located
on the IB4 board can be used to connect the NCU to your Local Area Network (LAN) for remote
access.
•
Distribution Only Bays
Each distribution only bay provides four (4) distribution buses. Each distribution bus accepts a
choice of 218-type circuit breakers and TPL-type fuses. A List 16 or 116 distribution only bay may
also be equipped with an optional distribution panel which accepts a choice of TPS/TLS-type
fuseholders or bullet nose-type circuit breakers. An indicator is visible from the outside of the
distribution only bay (at the top) which illuminates if a fuse or circuit breaker in the bay opens.
•
Rectifiers
The system contains rectifiers; which provide load power, battery float current, and battery
recharge current during normal operating conditions.
•
NCU Controller (if furnished)
The NCU controller provides power system 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 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
