The Smart-UPS SC 450VA 1U Rackmount/Tower (120V) from APC is a professional uninterruptible power supply designed to prevent blackouts, brownouts, sags, and surges from reaching your valuable equipment. It filters small utility line fluctuations and isolates your equipment from danger by internally disconnecting it from the utility line. When disconnected from the utility line, power is provided continuously from its internal battery until normal or safe conditions return or the battery is fully discharged. The unit also supplies battery-powered AC.
The UPS can be used in a tower or rackmount configuration. Front-access servicing also makes it easier to manage. This unit also offers RS-232 connectivity. It includes a $150,000 equipment-protection policy.
Protects the initial investment in the UPS when migrating from tower to rack-mount environment.
