What sort of stuff does an UPS do?
An UPS traditionally can perform the following functions: 1. Absorb relatively small power surges. 2. Smooth out noisy power sources. 3. Continue to provide power to equipment during line sags. 4. Provide power for some time after a blackout has occurred. In addition, some UPS or UPS/software combinations provide the following functions: 1. Automatic shutdown of equipment during long power outages. 2. Monitoring and logging of the status of the power supply. 3. Display the Voltage/Current draw of the equipment. 4. Restart equipment after a long power outage. 5. Display the voltage currently on the line. 6. Provide alarms on certain error conditions. 7. Provide short circuit protection.
