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.
