Product Description
Overview
Introduction
Lineage Power System rectifiers accept alternating current (ac) power and rectify it to produce direct
current (dc) power for powering external equipment (loads). Converters accept the dc output from rectifiers
or other sources and convert it to various regulated output dc levels also needed for powering external
equipment (loads). Batteries, generators, and UPS are used to provide backup power when ac is lost. When
batteries are used, they are connected in parallel for additional capacity along with the rectifier outputs
through appropriate breakers and contactor disconnects. DC power is distributed through distribution
panels with various protectors and contactors. These rectifiers, converters, backup systems, and distribution
are all managed by the controller. The following figure depicts a generic representation of the system
controller and its relationship in a power system. The components depicted and their associated features as
they relate to the system controller will be discussed in this manual.
