Safe-Fail Protection

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

Sag

A sudden, brief power undervoltage.

Simulated Sine Wave Output

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.

Sine Wave

A smooth, repetitive oscillation of AC power.

Sine Wave Output

Provides power protection to ENERGY STAR® 6.0 systems with Active PFC power supplies.

Single Phase Power

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

Sleep Mode

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.

Smart Battery Module

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

SMTP

Simple Mail Transfer Protocol (SMTP) is the standard for email transmission on the Internet.
