2.1 Overview
This chapter contains an overview of the system and a short description of the units in the
system.
The Guardian system is designed to meet rigid telecom applications with very high reliability
and flexibility for future expansion.
Power system unit is configurable to allow an installed capacity up to 11.6kW (5U version)
or 23.2kW (6U version) of rectifiers together with DC distribution, controller, and battery
backup.
Options include battery and load disconnects, AC surge protection and DC distribution.
The Guardian access system is ideal for radio base stations, broadband nodes and core sites.
The power system can be managed locally through messages and alarms displayed on the
LCD screen of the system controller, remotely using the PC-based PowComTM software, or
through a web browser with Ethernet connection.
