panels. (A maximum of 12 rectifiers, included in both the initial
and supplementary bays, may be used in this plant.)
If battery reserve is required, battery supplementary bays are
available which can each house up to two -48 volt strings of
Lineage

2000 VR Series 375 ampere-hour batteries. A
maximum of three supplementary bays or a total of six strings of
VR batteries can be added to the ECS battery plant providing a
total battery capacity of 2268 ampere-hours.

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:

The Lineage
®
2000 SR Series rectifiers are designed specifically
for applications where small size, low weight and ease of
installation are of overriding importance. The rectifiers utilize a
combination of switch-mode technology and forced air cooling
to achieve a significant reduction in size and weight over
conventional ferroresonant rectifiers. The plug in, connectorized
design of the rectifiers reduces installation time to minutes,
permitting easy growth and maintenance without service
interruption.
The Lineage
®
2000 SR Series 50 ampere rectifiers operate over
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 50
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 50
ampere rectifiers. The basic ECS plant is equipped with two
rectifier shelf assemblies for a total capacity of six SR Series 50
ampere rectifiers. Additional shelf assemblies and rectifiers are
orderable as separate list numbers. (See the Lineage
®
2000 SR
Series rectifier product manual for additional information on the
shelf and rectifier.)
