Introduction
The APC Uninterruptible Power Supply (UPS) is designed to prevent blackouts, brownouts, sags,
and surges from reaching your computer and other valuable electronic equipment. The 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 discharged.
