UPS Backup Battery System

How UPS work

An uninterruptible power supply (UPS), also known as a battery backup, provides backup power when your regular power source fails or voltage drops to an unacceptable level. A UPS allows for the safe, orderly shutdown of a computer and connected equipment. The size and design of a UPS determine how long it will supply power.

UPS Topologies

Different UPS topologies provide specific levels of power protection. A CyberPower UPS will belong to one of these three topologies: standby, line interactive, and double-conversion.

Protection

A UPS is typically used to protect hardware such as computers, data centers, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss. UPS units range in size from units designed to protect a single computer without a video monitor (around 200 volt-ampere rating) to large units powering entire data centers or buildings. The world's largest UPS, the 46-megawatt Battery Energy Storage System (BESS), in Fairbanks, Alaska, powers the entire city and nearby rural communities during outages.

Standby is the most basic UPS topology. A standby UPS resorts to battery backup power in the event of common power problems such as a blackout, voltage sag, or voltage surge. When incoming utility power drops below or surges above safe voltage levels, the UPS switches to DC battery power and then inverts it to AC power to run connected equipment. These models are designed for consumer electronics, entry-level computers, POS systems, security systems, and other basic electronic equipment.

Some manufacturers of UPS units categorize their products in accordance with the number of power-related problems they address.

A UPS unit may also introduce problems with electric power quality. To prevent this, a UPS should be selected not only by capacity, but also by the quality of power that is required by the equipment that is being supplied.

An uninterruptible power supply (UPS), offers guaranteed power protection for connected electronics. When power is interrupted, or fluctuates outside safe levels, a UPS will instantly provide clean battery backup power and surge protection for plugged-in, sensitive equipment, keep your equimpment and data safe.

UPS Battery For The Data Equinpments

Advantage

The primary role of any UPS is to provide short-term power when the input power source fails. However, most UPS units are also capable in varying degrees of correcting common utility power problems:

1. Voltage spike or sustained overvoltage

2. Momentary or sustained reduction in input voltage

3. Voltage sag

4. Noise, defined as a high frequency transient or oscillation, usually injected into the line by nearby equipment

5. Instability of the mains frequency 6. Harmonic distortion, defined as a departure from the ideal sinusoidal waveform expected on the line.
