Lab Notes

7 What is an in-line UPS?—An in-line UPS is a device that continuously provides power through a battery-powered circuit. Because it requires no switching, it ensures continuous power to the user.

7 What is a standby UPS?—A standby UPS is a device that quickly switches from an AC power source to a battery-powered source during a brownout or power outage.

7 What is an intelligent UPS?—An intelligent UPS is connected to a computer by way of a serial cable so that software on the computer can monitor and control the UPS.

7 What is a power conditioner?—A power conditioner is a device that regulates, or conditions, the power, providing continuous voltage during brownouts.
