1 Introduction
General
Information
This product manual describes the Lineage Power GCM2 and
GCM3 versions of the Galaxy Vector Controller. These
controllers are an integral part of various Lineage Power GPS
(Galaxy Power System) and OPS (Outdoor Power System)
series power plants. They provide control and alarm monitoring
functions over a digital serial interface that interconnects plant
rectifiers and converters. Control includes the setting of
converter output voltage, rectifier output voltage, current limit,
high voltage shutdown, rectifier restart, sequencing and boost
mode. This serial digital communication interface helps
automate the installation and setup process. For example, the
need to use potentiometers to separately set individual rectifier
and converter output voltage levels is eliminated. Versions of the
Vector Controller are available for both +24Vdc (GCM2) and -
48Vdc (GCM3) plants, including the 24V Flexent Wireless™
indoor and outdoor systems and H569-453 (+24V) / H569-454
(-48V) OPS systems.
The following Lineage Power rectifiers can interface with the
Galaxy Vector Controller:
Model Vdc Current
570A -48V 100A
595A, 595B, 595C -48V 200A
596A / 596D -48V 50A / 100A
596B +24V 100A / 125A
596F (Flexent) +24V 100A
NP -48 24-50A
Note: The Galaxy to Rectifier protocol supports many different
features and variables. Not all rectifiers support the complete
feature set.
