Power System

Power System
The library power system consisting of:
• One or two AC power distribution units (PDUs)
• One or two DC power supplies that provide voltage to the library
• An optional uninterruptible power supply

AC Power Distribution Units

Each power distribution unit (PDU):
• Operates within 100 to 127 VAC or 200 to 240 VAC at 50/60 Hz
• Distributes AC voltage to a library DC power supply
• Protects the library from overcurrent by circuit breakers

Uninterruptible Power Supply

The uninterruptible power supply (UPS) is an optional feature designed to
maintain continuous operation in the event of a power disruption. The UPS also
eases the effects of blackouts, brownouts, sags and surges in AC power.
The UPS
a power strip that allows you to connect up to eight additional components to
the UPS. If power fails, the UPS will supply power to the equipment connected
to the power strip until the batteries are exhausted.
