Reduces energy consumption by using an infrared (IR) smart sensor to shut down all home theater devices when the television remote has not been used for one or two hours. These power strips also include surge protection to prevent damage to sensitive electronic equipment by diverting excess voltage away from the television and connected devices during a power surge.

The time it takes UPS to switch from AC power to battery power.

A device that converts AC line voltage to a higher or lower value.

Secures an outlet by twisting and locking into place to prevent accidental disconnection.

U

The standard unit of measure for rack-mounted equipment. Equal to 1.75 inches in height per U. A device measuring 1U is 1.75 inches high. A device measuring 2U is 3.50 inches high.

UL requirements that cover indoor-use cord-and-plug-connected Health Care Facility receptacle outlet assemblies rated 250 V AC or less and 20 Amperes or less.

UL standard that applies to the safety of Medical Electrical Equipment.

Are set by Underwriters Laboratories (UL). CyberPower UPS systems are certified according to UL standards and meet strict testing requirements.

Occurs when voltage is lower than normal for an extended period of time without recovering, but not so low that the electronic device will not function. Two types of undervoltages are brownouts and sags. (Also known as under-voltage and undervoltage.)
