without transformer tap changes. A power factor correction
circuit incorporated in the design ensures 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
100-ampere rectifiers. The ECS plant can be equipped with up to
two rectifier shelf assemblies for a total capacity of six SR Series
100-ampere rectifiers. (See the Lineage
®
2000 SR Series
rectifier product manual for additional information.)
Batteries
The Lineage
®
2000 VR Series battery is designed specifically
for use in the ECS battery plant. The VR Series battery
maximizes space efficiency and provides the benefits of front
access, modular growth, ease of installation and maintenance
offered by the ECS battery plant system design.
The Lineage
®
2000 VR Series battery is a valve regulated design
incorporating many of the same technologically advanced
features as the highly acclaimed Lineage
®
2000 Round Cell
battery. It is a 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 Group 2 ECS plant. The compact physical
dimensions of the VR battery permit the installation of up to 750
ampere hours of +24 volt battery reserve in a single framework
space. (See the Lineage
®
2000 VR Series battery product manual
for additional information.)
Controller
The ECS controller (H569-420 Group 6) performs the
centralized monitoring, control and reporting functions for the
ECS battery plant. The basic ECS controller can monitor and
control up to six 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. The
