Runtimes

Runtimes
The UPS will provide battery backup to allow for a graceful shutdown in the event of a power failure.
Typical runtime on the APC SL20KFB2 Silcon 3 Phase UPS varies with the kW rating and the load. The
APC SL20KFB2 UPS provides a typical runtime of 36.7 minutes at half load and 10.7 at full load. If
additional run time is needed please contact your APC representative

Power Conditioning

Power Conditioning
The APC SL20KFB2 provides unparalleled power conditioning with its Delta-Conversion on-line double
conversion technology. This is especially helpful in regions were power is unstable.

Continuous Power during Short Interruptions of Input Power

Continuous Power during Short Interruptions of Input Power
The APC SL20KFB2 will provide battery backup to allow for continuous power to the connected
equipment in the event of a brief interruption in the input power to the UPS. Transaction activity will
continue during brief power outage periods as long as qualified UPS units are used to provide backup
power to the SPU, the Expansion Modules, and all disk and disk array products.

UPS Configuration Guidelines

UPS Configuration Guidelines
In general, the sum of the "Watt rating for UPS sizing" for all of the connected equipment should not
exceed the watt rating of the UPS from which they all draw power. In previous configuration guides, this
variable was called the "VA rating for UPS sizing." With Unity Power Factor, the Watt rating was the same
as the kVA rating, so it didn't matter which one we used. VA is calculated by multiplying the voltage times
the current. Watts, which is a measurement of true power, may be less than VA if the current and voltage
are not in phase. APC SL20KFB2 has Unity Power Factory correction, so the kW rating equals the kVA
rating. Be sure to add in the needs for the other peripherals and connected equipment. When sizing the
UPS, allow for future growth as well. If the configuration guide or data sheet of the equipment you want
to protect gives a VA rating, use this as the watt rating. If the UPS does not provide enough power for the
additional devices such as system console and mass storage devices, additional UPSs may be required.

Superdome

Superdome
The only qualified UPS available for use with Superdome is the APC SL20KFB2 Silcon 3 Phase 20-kW
UPS.
The APC SL20KFB2 can provide power protection for the SPU and peripherals. If the system console and
primary mass storage devices also require power protection (which is highly recommended) they may
require one or more additional UPSs depending on the total Watts. Make sure that the total watts do not
exceed the UPS's voltage rating.

Integration/Installation

Integration/Installation
