1 Introduction
General
Information This product manual (Select Code 167-790-041) describes the
H569-403 ECSBatteryPlant,which isshown inFigure 1-1.This
member of the ECS family of battery plants operates from a
nominal 208/240 volt ac, 50/60 Hz source. It offers a
600-amperetotal plantcapacity with a nominal 24-volt dc output
in a totally integrated energy system.
The basic plant consists of charge and discharge bus bars with
optional low voltage disconnect, a circuit breaker panel for
24-volt distribution requirements, an ECS controller, two
rectifier shelf assemblies which can connect up to six Lineage®
2000 SR Series +24-volt, 100-ampere rectifiers, and space for
four 24-volt to 48-volt, 10-ampere dc to dc converters and a fuse
panel for 48-volt distribution needs.
The plant's modular front-access design facilitates installation
and growth. Growth in plant output current capacity is achieved
by adding Lineage®2000 100-ampere, +24-volt rectifiers to
rectifier shelf assemblies. Adding functionality to the basic
controller is achieved through two optional circuit packs, one to
add microprocessor-based features and the second to add a
datalogger.
The ECS Battery Plant is compatible with virtually all
valve-regulated batteries that float within the range of 24
through 29 volts. In addition, the ECS plant is capable of
operating in a batteryless mode, making it suitable for those
applications where battery backup is not necessary or is
achieved through the use of an uninterrupted power supply
(UPS).

ECS Battery
Plant
Subsystems
Figure 2-2 illustrates the arrangement and interconnections of
the ECS Battery Plant subsystems from the ac input to the dc
output. These subsystems are described below:
Rectifier TheLineage®2000SR Seriesrectifiers are designed specifically
for applications where small size, low weight and ease of
installation are of overriding importance. The rectifiers utilize a
combinationof switchmode technology and forcedair cooling to
achieve a significant reduction in size and weight over
conventional ferroresonant rectifiers. The plug-in,
connectorized design oftherectifiersreduces installationtimeto
minutes, permitting easy growth and maintenance without
service interruption.
TheLineage®2000SRSeries 100-ampere rectifiersoperateover
208/220/240 Vac 50/60 Hz nominal single phase input range
without any necessary tap changes. A power factor correction
circuit incorporated in the design insures a power factor of 90
percent or greater for loads above 50 percent of the full load
rating. The rectifiers provide the ECS controller with a full
complement of status and alarm signals. The SR Series
100-ampere rectifier is both UL recognized and CSA certified.
The rectifier status and alarm signals, ac input, and dc output are
all connectorized. The rectifiers plug into a rectifier shelf
assembly that accommodates a maximum of three individual

Lucent Technologies Lineage®2000 ECS Battery Plant H569-403
Issue 4 February 1997 Product Description 2 - 7
100-ampere rectifiers. The ECS plant is equipped with two
rectifier shelf assemblies for a total capacity of six SR Series 100
ampere rectifiers. (See the rectifier product manual for
additional information on the shelf and rectifier.)
Batteries The ECS battery plant is compatible with virtually all flooded
and valve regulated batteries. The Lineage®2000 VR Series
battery is designed specifically for use in the ECS battery plant.
Selection of the VR Series battery enables one to maximize
space efficiency and fully realize the benefits of front access,
modular growth, and ease of installation and maintenance
offered by the ECS battery plant system design.
The Lineage®2000 VR Series battery is a valve-regulated

advancedfeaturesasthehighlyacclaimedLineage®2000Round
Cell battery. It isa compact, totally front access, modular battery
based on a unit cell architecture. The VR Series battery is
currently available in a 2 volt, 375 ampere-hour configuration
for use in the ECS plant. The compact physical dimensions of
the VR battery permit the installation of up to 1500
ampere-hours of 24-volt battery reserve in a single framework
space. (See the battery product manual for additional
information.)
Controller The ECS controller performs the centralized monitoring,
control, and reporting functions for the ECS battery plant. In the
H569-403, the basic ECS controller monitors and controls a
maximum of six SR 100/+24V rectifiers. The controller,
however, is capable of monitoring up to twelve rectifiers. It also
provides a single interface point for power alarm and status
reporting.
Two optional expansion circuit packs are available to upgrade
the ECS controller: a microcomputer board equipped with a
powerful 16-bit microprocessor, and a datalogger board. The
microcomputer board adds sophisticated firmware features such
as remote communications, alarm history, and statistics. This
board is available as Group 5 or 7 on H569-403. Group 7 is the
same as Group 5, with the addition of a voice response feature.
The datalogger board may be used in conjunction with the
microcomputer option to provide general purpose ac and dc
voltage and current monitoring and control. This board is
available as Group 8 or 9 on H569-403. Group 9 is the same as

Lucent Technologies Lineage®2000 ECS Battery Plant H569-403
2 - 8 Product Description Issue 4 February 1997
Group 8, with the addition of a remote termination panel
allowing external connection to the board from outside the
controller. (See the ECS controller manual for further
information.)
DC-DC Converter The Lineage®2000 KS2383224-volt to -48-volt dc-dc converter
system utilizes 50KHz technology to provide a reliable and
economical means of obtaining closely regulated and filtered
-48-volt dc power when only one primary source of +24-volt dc
power is available.
The dc-dcconvertersystem consists ofKS23832 convertershelf
assemblies equipped with one or two KS23832 10-ampere
+24-volt to -48-volt converters. Amaximum of two shelves with
four converters may be equipped per bay. Group 41 provides a
converter shelf equipped with two converters and Group 42
provides a converter shelf equipped with one converter.
Converters should be sized with n+1 redundancy. This extra
reserve not only provides backup to your operating converter but
also provides the necessary energy required to operate fuses.
Distribution to the -48-volt load is provided via a meter and fuse
panel.
The converter shelf assembly has mounting brackets for
standard 26-inch relay rack mounting. Each converter module
contains a blocking diode, low input voltage shutdown, current
limiting, and high voltage shutdown with automatic restart. The
converter shelf assembly is equipped with major and minor
alarms. The converter shelf assembly has two Form C contacts,
one for converter major and one for converter minor. When one
converter fails, the converter minor relay will operate and when
two converters fail, the converter major relay will operate. For
more details, refer to the KS23832 converter product manual.
DC Distribution The ECS H569-403 distribution includes the plant charge and
discharge bus bars, plant shunt, LVD/R contactor, and
associated circuitry. Space below these items accommodates
circuit breaker panel for 24-volt distribution. A meter and fuse
panel is also available for 48-volt loads when the plant is
equipped with 24-volt to -48-volt converters. A complete
