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- mentacrossEthernetorTokenRingbasedLANsorWANscapableofroutingIPmessages. 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.
