1. DC Power for
Business-Critical Continuity
The SCU provides detailed information and alarms regarding the condition and
status of the Telecom sites's power plant. If maintenance and site visits related to the
power plant are based upon this information, they can be optimized to save both
time and money, especially if the site is located remotely.
The SCU is a hot pluggable unit optimal for use in both embedded or stand-alone
applications. It provides remote monitoring, configuration, status information and
control of the DC power plant's voltage, current and alarm levels.
The SCU is a control unit designed for global use, and it withstands high telecom
standards, and provides great reliability and availability.
In order to obtain detailed and extensive monitoring and control of auxiliary
equipment on site, the power plant can be upgraded from a SCU to a ACU( Advanced
Control Unit) by means of a simple swap of the hot pluggable SCU and ACU units.
Minimized installation time-as a
result of easily configurable file
upload/download
High quality failure information-due
to intelligent alarm setup through
using PLC
True hot plug installation of
controller unit-thanks to simplified
communication cable connection
installation to a separate connection
board
Quick failure analysis-owing to
storage of the 200 latest alarms
Extend battery life-for advanced
battery management
