The Smart-UPS SC 420VA (120V) from APC provides power protection and battery backup for office computer systems. The UPS provides surge protection and battery backup via 4 outlets. It yields an average output power capacity of 420VAC at 260 watts and the battery lasts up to 14 minutes at half-load capacity.
The UPS also features RS-232 serial communication and RJ-45 data line protection. APC offers guaranteed protection from surges and spikes with their lifetime $150,000 Equipment Protection Policy. These features make the Smart-UPS SC an excellent choice to provide power and battery backup for your office PC.
Boost and Trim Automatic Voltage Regulation (AVR)
Gives higher application availability by correcting low and high voltage conditions without using the battery (not available on all models).
Intelligent Battery Management
Maximizes battery performance, life, and reliability through intelligent, precision charging.
Protects connected loads from surges, spikes, lightning, and other power disturbances.
Temperature-Compensated Battery Charging
Prolongs battery life by regulating the charge voltage according to battery temperature.
Automatic Restart After UPS Shutdown
Automatically starts up the connected equipment upon the return of utility power.
Periodic battery self-test ensures early detection of a battery that needs to be replaced.
Disconnected Battery Notification
Warns when a battery is not available to provide backup power.
