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 & load circuit breaker trip sensing
• battery charge current limiting
• short circuit and reverse polarity protection
• battery temperature sensing
• n+1 redundant rectifiers
• low voltage disconnection
• a monitoring and control module (Controller)
• automated/remote battery discharge testing
• super capacitor backed real-time system clock
• accurate temperature compensated Float and
Equalization voltages
• optional remote communication capability,
including web-based protocols
• optional modules for monitoring AC power and
battery cell voltages
• all rectifiers and the controller are hot-swap and
plug-and-play capable
• optional AC distribution
