2 Product Description
Overview
Lineage Power 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 typically used to provide
backup power when ac is lost. Batteries are connected in parallel for additional capacity with the
rectifier outputs through appropriate breakers and contactor disconnects. DC power is distributed
through distribution panels with various protectors and contactors. These rectifiers, backup
systems, and distribution components are all managed by the Pulsar Edge system 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.
