Introduction

2.0INTRODUCTION

Congratulations on your choice of the Liebert PowerSure™ PSI Uninterruptible Power Supply (UPS). It provides conditioned power to microcomputers and other sensitive electronic equipment.

Upon generation, AC power is clean and stable. However, during transmission it may be subject to voltage sags, spikes, or complete power failure which may interrupt computer operations, cause data loss, or even damage equipment. The PowerSure PSI protects equipment from these disturbances.

The PowerSure PSI comes in nominal power ratings of 1000, 1440, 1920, 2200 and 3000 VA. Refer to the Specifications section for details.

The PowerSure PSI is a 2U, line-interactive UPS that may be installed in a rack or used in a tower configuration. A line-interactive UPS continuously conditions and regulates its output voltage, whether utility power is present or not. It supplies connected equipment with clean, sinewave power to simulate the power generated by the utility. Sensitive electronic equipment operates best from sinewave power.

For ease of use, the PowerSure PSI contains Status Indicators to display Load Level, Battery Level, Buck/Boost, Over Temperature and Battery. It also provides self-diagnostic tests, a combination ON/ Alarm Silence/Battery Test button, an OFF button and Voltage Programming button.

The PowerSure PSI has USB, DB-9 (RS232/contact closure) and Intellislot interface ports for commu- nications between the UPS and a LAN server or other computer systems. The DB-9 port provides detailed operating information including voltages, currents, and alarm status to the host system when used in conjunction with Liebert’s MultiLink™ software. MultiLink software can also remotely control UPS operation. The USB port provides detailed operating information and alarm status to the host system when used in conjunction with the Liebert Human Interface Device (HID) and Microsoft Power Manager software.
