1.0 Introduction
1.2 SmartBoost
SmartBoost allows continuous on-line operation during extended brownouts or low line
voltage conditions. The UPS compensates for the reduced line voltage by boosting the
load voltage to a value 12% above the input. Reliability is enhanced because the limited
battery capacity is saved for complete utility failures.
1.3 Battery replacement indicators and test
The UPS provides both visual and audible Replace Battery indications. The indications
are based on the result of an actual load test on the battery. By exercising the UPS’s battery
during a startup test, the UPS is able to detect a weak battery before it is put into service.
In applications where the UPS is not turned off daily, or where the UPS is purposely left
operating unattended, the UPS automatically conducts this self test every 14 days.
1.4 Remote interfaces
The UPS provides a remote computer interface capable of full bidirectional RS-232
communications. When combined with PowerDoctor UPS monitoring software and a
serially connected local DOS PC, power quality related events can be logged. Power-
Chute plus offers all the features of PowerDoctor, plus the ability to control orderly and
unattended network or multi-user computer system shutdown during an extended
power outage. Also available for the UPS is the SNMP (Simple Network Management
Protocol) Adapter to provide load type independent remote monitoring and manage-
ment across Ethernet or Token Ring based LANs or WANs capable of routing IP messages.
Using any standard Network Management System (NMS) and the SNMP Adapter, the
UPS becomes manageable through a single familiar interface - from across your building
to across the world.
1.5 Extended capabilities
Via the UPS's remote interface, the user can access advanced monitoring, power manage-
ment and operation customizing functions. Monitored parameters include line voltage,
line frequency, output power, output voltage, battery capacity, battery voltage and
internal temperature. Power management functions include scheduled shutdown,
power failure simulation, and remote turn off. UPS functions that can be customized
include the automatic self test and low battery warning intervals; shut down, turn-off
and turn-on delay intervals; transfer voltage; utility fault sensitivity; and activation of
the audible alarm.
