You probably already know Uninteruptible Power Supply (UPS). However, often people only know of two types of UPS that are most easily seen in the market.
The second type is the type of standby UPS and the UPS type online. In fact, UPS still has a few other types of advantages and disadvantages of each.
American Power Conversion (APC), a global leader in services critical power and cooling services are also popular with UPSnya products, provides information and tips about various UPS so that users can get to know and choose the UPS that according to his needs.
UPS is divided into several types which produce different performance characteristics:
Standby
Line Interactive
Double Conversion On-Line
Delta Conversion On-Line
Standby type UPS
This type usually used by home users to juxtaposed with their PCs. UPS with this type capable of filtration to-noise and power flow management, in addition to the efficient design, small size and cheap.
Line Interactive UPS type
This type of UPS is the most frequently used in small business units, web developers, and a number of servers that are in government departments. This is because in addition to having high levels of reliability, this type also have the ability to adjust well enough voltage.
UPS has an inverter is always connected to the output of the UPS system to change the power from batteries into AC. In normal circumstances, the inverter will perform battery charging. While in power outages, Transfer Switch will shut down and drain power from the battery to the UPS output.
Inverter position that is always connected to the output filter to give extra power. This is what makes this type of UPS with widely used for servers and electrical conditions are not too good.
Double Conversion type UPS On-Line
This type is most common for UPS with more power than 10kVA. This type has similarities with the type of Standby. Only this type has a main power source located on Inverter, not on an AC power source.
In this type, cut off the main electricity supply will not trigger a transfer switch for AC electrical current that enters at the middle input to the battery charging that provides power to the inverter is located at the output.
Therefore, when the AC electric current is interrupted, the flow of energy will be transferred without taking a break when the transfer occurs. This type of UPS shows performance above average. Can be said of this type of approach the ideal of a UPS, unfortunately, this type of heat high enough.
Delta Conversion type UPS On-Line
Almost the same as Double Conversion type, type Delta used to always supply the inverter voltage. As power supply is interrupted, this type do the same with Double Conversion type.
Delta Conversion has two functions, the first is to control the input power characteristics. Whereas the second function is to control the flow of inputs to direct the process of filling the battery system.
Thing to remember is that this type minimize wasted energy. In addition, he has a high compatibility of the various types of generators and reduce the need for the use of cables.
In summary, advantages and disadvantages of UPS types can be seen below:
Standby Advantages: Low cost; high efficiency; compact design.
Disadvantages: battery remains in use as power outages; not suitable for use in the 2kVA.
Description: The most suitable for personal users.
Line Interactive Advantages: high reliability; high efficiency; good voltage adjustment.
Disadvantages: not suitable for use over 5kVA.
Description: UPS type most often used in electrical conditions of uncertainty.
Double Conversion On-Line Advantages: adjusting the voltage is very good; easy to be connected in parallel.
Disadvantages: Low efficiency; they're expensive for the type of power under 5kVA.
Description: UPS is the ideal approach, but produce high enough heat.
Delta Conversion On-line Advantages: voltage adjustment very good; high efficiency.
Disadvantages: not suitable for use under 5kVA.
Description: High efficiency devices prolong the life cycle when used on large systems.
