This feature cuts power to connected equipment when the surge protector cannot provide protection anymore.


A sudden, brief power undervoltage.

Uses pulse wave modulation to generate a stepped, approximated sine wave to supply cost-effective battery backup power for equipment that does not require sine wave output.

A smooth, repetitive oscillation of AC power.

An output waveform is a way to describe the type of electric power being generated. Utility power is delivered with a smooth continuous transition between positive and negative polarity. It is considered sine wave output.

A benefit of sine wave output is it provides power protection to ENERGY STAR® 6.0 computer systems with Active PFC power supplies.


Refers to the distribution of alternating current electric power using a system in which all the voltages of the supply vary in unison.

The state in which a computer’s monitor and hard disk turn off to save energy. In sleep mode, all unsaved data and files will be lost if a power problem occurs.

Improves and extends the functional life of a UPS battery and reduces excessive heat during work cycles by using a three-cycle charging process.
