UPS Technology

Which UPS Is Right For Your Application?

The approach to power protection revolves around the nine most common power problems present in any work environment. You can choose from a variety of power protection devices with varying levels of effectiveness and price that will shield critical data and equipment from some or all of the 9 power problems.

In general there are three types of UPS's: level 3, level 5 and level 9. To choose the UPS that is right for you, first determine the level of power protection that is needed. It is obvious that the ideal is to provide the full protection from all power problems afforded by a level 9 UPS. But there may be applications where the power quality is known to be high, or where the load is not considered critical, or where budget considerations force a compromise.

Level 3 UPS technology

Level 3 UPSs are standby or offline designs that are intended to provide a low price solution for power failures, power sags and power surges. Utility power is provided during normal operation. Utility voltage and frequency changes are not regulated by the level 3 UPS and pass through to the equipment. When voltage or frequency changes become too severe, the level 3 UPS inverter converts DC battery power to AC power to run the equipment.

Level 3 UPSs provide protection from simple power problems as described in items 1,2 & 3 under  9 power problems.

Note: Level 3 does not provide protection from items numbered 4,5,6,7,8 & 9 listed under    9 power problems.

How do you know if you have a level 3 UPS?

The most common terminology used to descried a level 3 UPS is "Stand-By UPS" or Back-up UPS" (Back-UPS). Most models do not provide a "pure sinewave", it is a "stepped approximation to a sinewave". Runtime is typically limited to the internal batteries (in most cases 3-8 minutes runtime at full load). In most cases there is a 3-5 millisecond delay to transfer to battery. Price will typically range from $50.00 - $300.00 depending on the brand. VA ratings will typically range from 350va - 1500va.

What is the typical application of a level 3 UPS?

The most common uses are home PC's, work stations and other non-critical equipment. Call us at 800-706-7009 for the right UPS for your application.

What brands does Power Factor Inc. Offer in a level 3 Product?

Minuteman, Powerware and many others. Our sales staff can help you find the best value for your application.

Level 5 UPS technology

Level 5 UPSs offer line-interactive technology and provide basic power protection at mid-range prices. In addition to protection against  power failures, power sags and power surges, level 5 UPSs protect against undervottage and overvoltage. This design offers low- grade voltage regulation by 'bumping" the utility voltage up or down before passing it through to your electronic system. During the UPS voltage changes, the level 5 uses the battery for regulation.

Although level 5 UPSs provide more voltage regulation than level 3, battery life is often sacrificed. The number of transfers to and from the battery by the level 5 design exceeds that of the level 9 by as much as 10 to 1 during brownouts and power surges.

Note: Level 5 does not provide protection from items 6,7,8 or 9 listed under   9 power problems.

How do you know if you have a level 5 UPS?

The most common terminology used to descried a level 5 UPS is "Line interactive" or "Smart-UPS". Some manufacturers such a APC may use the term "Smart-UPS" for both their line-interactive (level 5) and on-line (level 9) UPS's. Most models do provide "pure sinewave" output. Some models may offer extended runtime by using additional battery packs. In most cases there is a 3-5 millisecond delay to transfer to battery. Price will typically range from $150.00 - $5000.00 depending on the brand and runtime. VA ratings will typically range from 500va - 5000va.

What is the typical application of a level 5 UPS?

The most common uses are home PC's and workstations that are in a poor power environment, some servers in a good power environment, non-critical servers and equipment. Call us at 800-706-7009 for the right UPS for your application.

 

What brands does Power Factor Inc. Offer in a level 5 Product? Minuteman, Powerware, GE Industrial and many others. Our sales staff can help you find the best value for your application.

Level 9 UPS technology

 Level 9 UPSs are designed to provide complete power protection These Online UPSs protect against all types of power problems by continuously using the inverter to create 100% new, clean, regulated AC power for your systems. Equipment is isolated from all types of power problems when supplied by an Online double conversion UPS.

Level 9 UPSs isolate equipment from harmonic distortion and are strongly recommended for critical applications  that must meet the 5% maximum harmonic requirement stated in major computer manufacturer specifications and installation guides.

Battery conservation is an essential factor in your decision to purchase a level 9 UPS. Level 9 UPSs use the battery less than any other UPS technology, increasing the life of your UPS battery.

Note: Level 9 provides protection from all 9 power problems listed under 9 power problems.

How do you know if you have a level 9 UPS?

The most common terminology used to descried a level 9 UPS is "On-Line", "Double Conversion" or "Smart-UPS". Some manufacturers such a APC may use the term Smart-UPS for both their line-interactive and on-line UPS's. Most models do provide "pure sinewave" output. Most models offer extended runtime by using additional battery packs. In all cases there is no break in power.

Price will typically range from $500.00 - $30,000.00 for a single phase UPS depending on the brand and runtime. VA ratings will typically range from 500va - 20Kva for single phase UPS's. Three phase UPS's Typically range from $20,000 - UP and Kva ratings from 10Kva - 500Kva.

What is the typical application of a level 9 UPS?

The most common uses are for critical applications such a servers and other expensive equipment. Call us at 800-706-7009 for the right UPS for your application.

What brands does Power Factor Inc. Offer in a level 9 Product?

Minuteman, Powerware, GE Industrial, LPC and many others. Our sales staff can help you find the best value for your application.
