Introduction
The Standard Control Unit (SCU) provides detailed information and alarms regarding
the condition and status of the telecom site'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.
Designed for global use, the SCU withstands high telecom standards, and provides
great reliability and availability.
