Introduction

The APC Uninterruptible Power Supply (UPS) is designed to prevent blackouts, brownouts, sags,
and surges from reaching your equipment. The uninterruptible power supply (UPS) filters small util­ity line fluctuations and isolates your equipment from large disturbances by internally disconnecting
from the utility line. The UPS provides continuous power from its internal battery until the utility
line returns to safe levels or the battery is fully discharged.
