Guide For UPS

 


New to the world of UPS systems? Consider this UPS buying guide your introduction to the basic concepts behind UPS systems and which type will work best for your needs.

What is UPS System?

A UPS Battery, in its most basic form, is a battery backup power system that provides enough power to properly shut down equipment when utility power fails. This helps prevent data loss and reduces the stress caused by difficult shutdowns on your electronic devices. UPS is also a surge protector that protects equipment associated with power problems, such as surge or abnormal voltage, that can damage the performance of electronic components and equipment, shortening or affecting the lifespan.

Why do you need a UPS system?

In the case of a blackout, the UPS immediately switches to battery power to provide a continuous power source for the length of the battery. Battery life can vary by system and depends on what amount of power you use. Battery backup gives you time to power off sensitive equipment, servers, or even video game consoles without loss of data or progress. Various UPS systems provide some level of protection against other power problems that may arise.

What are the types of UPS systems?

UPS systems have three different topologies, or categories, depending on what type of power protection you need and they are:

Ø Standby

Ø Line-Interactive

Ø Double-Conversion

What are common electrical problems?

Below are definitions of potential power problems you may experience:

1.  Surge

A brief, but intense, spike in lightning, usually caused by a lightning strike. Surges can damage and destroy electronics, and a rapid "spike in electricity" or spike in voltage and current can damage circuit boards and components.

2.  Blackout

Power outages anywhere from seconds to days. These are usually caused by severe weather, utility power outages, accidents and power grid failures.

3.  Brownout

An intentional or unintentional drop by voltage for an extended period of time. In emergency situations, power companies may lower your electrical voltage to reduce stressed resources and avoid total blackouts.

4.  Voltage sags

A sag is also a type of under voltage, but, unlike a brownout, it is sudden and brief.

5.  Over voltage

Occurs when the incoming voltage is higher than normal and lasts longer than a surge but not high enough to be classified as a surge or spike.

Advantages of UPS

1.  At home

The electronic devices you depend on every day for communication, security, and entertainment are in danger of damage and failure due to unexpected blackouts, voltage fluctuations, or other power disruptions. A UPS provides battery backup power and protection for electronic equipment, including:

Ø Wireless networking equipment (routers, modems)

Ø Computer

Ø Television

Ø Security systems

Ø Gaming consoles

Ø Mobile devices

2.  For businesses

Downtime due to power outages is frustrating for anyone but can be financially crippling for a business or organization. Every year, billions of dollars are lost due to downtime due to power outages that could have been prevented by UPS. For Fortune 1000 companies:

Ø Average annual cost of unplanned downtime, $1.25-$2.5 billion

Ø Average hourly cost of infrastructure failure: $100,000

Ø Average hourly cost of critical application failure: $500,000-$1 million

Small to medium-sized businesses may be at the most financial risk due to their limited ability to generate revenue during downtime.

How should a UPS to look like?

UPS systems have form factors. The form factor of a UPS indicates the size and shape of its housing. The most common are 3 types:

Ø Desktop or compact

Ø Tower or mini tower

Ø Rack mount

When choosing a form factor, the main consideration is where you are going to use it.A tower or mini-tower will have a pleasing aesthetic design which makes it a great choice for sitting on top of a desk or table. Rack mount UPS works well in server rooms.
