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

management and operation customizing functions. Monitored parameters include

available run time, 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.
