2.1 GENERAL DESCRIPTION

RT9 Power shelf systems are turn-key DC uninterruptible power supply solutions (DC UPS) for powering 24VDC
or 48VDC telecommunications and industrial equipment. The Power shelf provides integrated battery management
functions for a range of battery types (VRLA, flooded Lead-acid, NiCad, Ni-MH, Li-polymer) to enable easy
commissioning of a DC UPS or it can be used as a standalone DC source when no batteries are used.
The Power shelf provides the following integrated features:
•
battery (& load) distribution
•
battery charge current limiting
•
battery temperature sensing
•
low voltage disconnection
•
automated/remote battery discharge testing
•
accurate temperature compensated Float and
Equalization voltages
•
optional modules for monitoring AC power and
battery cell voltages
