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.
