01. What's UPS?
UPS stands for "Uninterruptible Power Supplies", it can provide instant backup power in the critical moment while blackout, brownout, or other power problems strike your equipment. The power problems include brownout, sag and spike, surges, and noise interference etc. When surges occur, it may intrude your computer via AC outlet or phone line, aim first at your modem or motherboard, go next chips, and finally affect your precious computer hardware components. After that, your systems in use may suddenly shut down resulting in data loss. Can you bear your long-term efforts suddenly disappear within shortly one second? Can you accept your expensive machine is getting unaware of breakdown? The more power problems occur, the more cost you'll pay.

UPS has been designed for eliminating the above annoying problems. First, UPS can transfer AC input voltage affected frequently by external factors to the acceptable voltage range that your complicated machines needed, and provide a stable power supply. Second, UPS is promptly providing consistent battery backup within 10 seconds while blackout or brownout occurred protecting your systems from shutdown unsafely and data loss. Third, when you live in with unstable weather or bad power supply environment, you must have a UPS to protect your sensitive machines against surge, spike, and lightning striking your equipment.

 
02.Why do I need UPS?
The below is part of articles showing you the importance of power problems from other survey agency or corporate issued:

  • Power problems are the second leading and most preventable cause of computer downtime.
    (Source: HP Whitepaper: Increasing Single System Availability)
  • Power problems are the leading cause of data loss, 15 times more frequent than computer
    viruses.(Source: Contingency Planning)
  • Power problems (surges and lightning) were the number one cause of desktop computer loss in 2001 and 2002. (Source: Safeware. The Insurance Agency, Inc.)
  • Power disturbances account for about one third of all server failures.(Source: IDC) · Sags in power supply can cause up to 87% of computer crashes.(Source: AT&T Bell Labs)

 
03.What kinds of equipment UPS can protect?
UPS is usually applied in complicated equipment meeting the demands of high-quality and continuous power to PCs, workstation, monitor, fire-wall equipment, and medical apparatus etc. The below is the most common application by UPS:

  • PC / Workstation: Including monitor, modem or external peripherals
  • Server
  • Network Device: Including hubs, routers, and switches
  • Telecom Device: Including home systems, monitoring systems, alarms, and POS
  • Data Storage Array: Including RAID system and tape drives
  • Other Storage: Such as fax machine, scanner, and projector etc.

05.What size UPS should I choose?
First, you should determine the power requirements of your equipment as follows:

Insure that the equipment plugged into the battery power-supplied outlets does not exceed the
UPS unit's rated capacity (1500VA/1000W for PR1500E, 2200VA/1600W for PR2200E). If rated unit capacities are exceeded, an overload condition may occur and cause the UPS unit to shut down or the circuit breaker to trip.

If the power requirements of your equipment are listed in units other than Volt-Amps (VA), convert
Watts (W) or Amps (A) into VA by doing the calculations below. Note: The below equation only calculates the maximum amount of VA that the equipment can use, not what is typically used by the equipment at any one time. Users should expect usage requirements to be approximately 60% of below value.

Second, estimate the power requirements as follows:

  • _______ Watts (W) x 2.0 =_______ VA or _______ Amps (A) x 230 = _______ VA
  • Add the totals up for all pieces of equipment and multiply this total by 0.6 to calculate
    actual requirements. There are many factors that can affect the amount of power that your computer system will require. The total load that you will be placing on the battery-powered outlets should not exceed 80% of the unit's capacity.

01.How to choose your UPS?
The followings are some suggestions for you to choose a suitable UPS:

  • Understand what level UPS can totally meet your requirements and budget. For instance, if you need high quality power supply and have affordable budget, On-Line UPS may be your first choice.

  • Search for current UPS products on the market via internet searching engine or local electronic retailer, and then insure what kinds of specifications you need. The key factor including:
    ‧ Voltage volume
    ‧ UPS runtime
    ‧ Functionality
    ‧ Efficiency
    ‧ Battery replacement
    ‧ Operating systems supported


  • Besides surveying technical specifications, a reliable UPS brand is also a necessity. Some advices to value a UPS brand are listed below:
    ‧ Reliable reputation and solid financial structure
    ‧ R&D innovative capability and self-production ability
    ‧ Complete technical support and real-time service
    ‧ Products with qualified safety certificates like TUV, UL, and CSA etc.
    ‧ Manufacturing factories with qualified standard procedure certificates like ISO9001 and
         ISO9002

Environment
  • This series is used in some places with poor power quality, such as industry area or suburb district where power quality is strong demanded.

Amps An amp is the basic unit of electric current. It measures the amount of current that a device needs to operate. Your computer's monitor will show a rating in amps, signifying how much power it uses.
Blockout A blackout means input power breaks off for a period of time. An Unexpected blackout may make your systems shutdown unsafely, data loss, and even hard drive crashes.
Brownouts A brownout is a reduction of your incoming voltage. Brownouts are the most common form of power problems, accounting for over three-quarters of all power problems. When brownouts occur, the lower voltage causes your computer system to work harder then it has to. This can cause excessive wear and premature failure of critical components.
Joules A joule rating is a unit of energy. Joule ratings are given on UPS systems and surge protectors to provide an idea of how much surge protection they provide. CyberPower units list the joule rating of each outlet. Many times you will see the total joule rating (number of outlets x rating for each outlet) listed as the joule rating for the unit. Look for units that provide joule ratings of 400 or greater to insure exceptional protection for your system.
Lightning It only takes one lightning strike to cause catastrophic damage to your system!
Line Noise Line noise is interference from other electrical appliances such as hair dryers, microwaves and vacuums. Line noise can also be caused by fluorescent lighting. A common example of line noise would by the "snow" that appears on your TV screen when running other appliances.
Power Failuer A power failure is a complete interruption of electrical power. This can cause damage to your hardware, as well as loss of data. When the power is restored, you run a real risk of post-power failure surges, spikes and sags.
Sag Also named brownout, means a short-term decrease in incoming voltage. Sag is one of the most common power problems, it may lead to your computer lacking of enough power to function, and result in keyboards frozen, system crashes, and data loss.
Surge A short-term increase in incoming voltage, typically lasting at least 1/120 of a second. Surges are usually caused when items that draw a large amount of electricity (air conditioners, refrigerators, copiers, etc.) are turned off. The extra power that these items were using is then released back into the power lines. Surges occur frequently, but can be of such short duration, that you may not notice them. Surges can cause damage to your computer, as well as corrupt your data.
Spike A spike is an instantaneous increase in voltage. It most often caused by a nearby lightning strike, sometimes by power coming back on after a blackout. A spike may get into your equipment through AC, network, serial or phone lines, and then cause aborted modem transfer, microchip failures and "fried" hardware.
Voltage Sag A voltage sag is another name for a brownout.
Volt-Amps When purchasing a UPS system, you need to know how much capacity you need. This capacity is measured in volt-amps. To determine the number of volt-amps that you need, take the number of amps multiplied by 120. If the measurement is in watts, multiply by 1.82. For example, if your monitor uses 2 amps (2 x 120 = 240) and your computer uses 100 watts (100 x 1.82 = 182) the total volt-amps needed would be 407 (240 + 182 = 422).
Watts A watt is a unit of power. For example, your computer power supply is listed in watts because it shows the amount of power that it outputs to your computer.
