Introduction

The APC Smart-UPS® RT is a high-performance, uninterruptible power supply (UPS) that provides
protection for electronic equipment from utility power blackouts, brownouts, sags and surges. The
UPS filters small utility line fluctuations and isolates electronic equipment from large disturbances
by internally disconnecting from utility line power. The UPS provides continuous power from the
internal battery until utility power returns to safe levels or the battery is fully discharged.
