POWER SOLUTIONS

Some industry terms to assist with the understanding of Power requirements:

Alternating Current (AC)

Current that alternates from positive to negative. AC is the normal current used to power most devices in homes and businesses

Direct Current (DC)

Electricity where current flows in one direction, such as from a battery

Efficiency

The ratio of output energy to input energy. For uninterruptible power supplies (UPS’s) it is the amount of energy lost in the form of heat during DC to AC inverter operation

Inverter

A device that converts DC power to AC power

Hard Wired

Power attached to UPS directly using screw lugs

Single Phase

AC Power 220V

Three Phase

AC power of Three (3) Live connections and a single Neutral, combined to carry High Voltage of 380V and greater.

Surge Suppressor

A device that diverts and/or diminishes excessive current and voltage from the AC power line, which can damage sensitive electronic equipment

Uninterrupted Power Supply (UPS)

A device that provides continuous power to its load, regardless if the commercial utility’s power is present or not

UPS (Standby)

A standby UPS, also called an “Offline UPS”, is the most common type of UPS. It monitors the power line and switches to battery power as soon as it detects a problem. The switch to battery (transfer time), however, can require several milliseconds, during which time the computer is not receiving any power

UPS (Line Interactive)

The line interactive UPS is a standby UPS that “interacts” with the AC power line to smooth out the wave forms and correct the rise and fall of the voltage. They also offer surge protection

UPS (On Line)

An on-line UPS avoids momentary power lapses by constantly providing power from its own inverter, even when the power line is functioning properly.
