AC Utility Power

The power supplied by a standard wall outlet. Alternating Current (AC) is the common form of electricity.  

Active PFC Compatibility

A feature of UPS systems that delivers sine wave output to prevent unexpected shutdowns or component stress for connected devices with Active PFC power supplies.

Advanced Power Strip (APS)

An advanced power strip or APS stops electronic devices from drawing power when not in use or in standby mode. Computers operate in a standby modes when idle which make them convenient to power up quickly but then use significant amounts of energy when no one is actually using them. A television is in standby mode when it is plugged in and powered off making the available for the remote control to turn them on.

Alternating Current (AC)

The direction of an electric charge that is flowing in a circuit which is constantly being reversed between positive and negative. In the U.S., the direction of AC reverses 60 times per second.

Amp (Ampere)

The standard unit of measure for electrical current. Defined as the amount of electrical flow equal to one coulomb per second.

Apparent Power

The product of the applied voltage and current in an AC circuit. Apparent power is measured in VA (volt-ampere).

Audible Alarms

Identify conditions which may affect operation, such as overloads and low battery.

Automatic Shutdown

Protects connected electronics with the integrated circuit breaker which automatically switches off in the event of an overload that exceeds a model’s ability to suppress the signal. For RMCARDS, automatic shutdown protects servers and workstations from data loss due to power failure.

Automatic Voltage Regulation (AVR)

Provides clean, consistent AC power by automatically regulating low voltages and over voltages, within defined tolerances, when incoming utility power has minor fluctuations.
