Summary: UPS devices that can be placed by your PC on your desktop are the most commonly used ones as they fit conveniently and will give power to the PC in the event of a power failure. If you want to be sure you have total protection then this is not a good idea, as it does not give complete protection against brownouts and spikes. This is the reason why you need to have a proper UPS system that can supply energy as well as shield your PC.
In order for your equipment to stay connected during an unexpected power failure, it is necessary to have the backup of a UPS system. This basically transforms AC power from the main source to DC power which is stored in the battery and then back to the AC power which is supplied to your connected equipment. This kind of an UPS system is capable of providing an uninterrupted power supply along with complete security against brownouts and spikes.
UPS systems generally refer to more than one UPS working in conjunction with another UPS, thereby providing superfluous energy and better security to equipments. Power is stored in the UPS system in batteries, most common of which are the lead acid batteries that can last anywhere from 4 to 5 years.
The capacity of these UPS power supplies is determined by the usage requirement that can be evaluated by the number of equipments that will ultimately use its power source. In order to maintain the system and to ascertain proper service times it is essential to scrutinise it at regular intervals. After all, it’s supporting a vast number of pieces of equipment.
Unlimited power however, cannot be provided to the UPS systems and maybe restricted to a condition of energy for perhaps only a few days or a week. It is therefore necessary to have a back up resource such as a generator. The uninterrupted power supply is provided to a vast number of equipments by the two working together; this safeguards them from disruptions like brownouts and spikes.
There are three types of UPS systems available that include on-line, line interactive and standby UPS systems. The standby UPS is the least expensive and can provide protection for up to 20 minutes. However, it consists of rudimentary attributes offering only surge defence and backup energy. Due to the fact that this does not have the potential to self-test or the ability to monitor, it makes it very vulnerable to any sudden unexpected power surges. If you are looking for something reliable, then this should not be considered.
The line interactive UPS is very similar to the standby UPS. The main difference being it consists of an autotransformer that can add or take away power coils, which in turn is able to control the output of the electrical energy of the transformer. It can keep back high voltage surges and low voltage brownouts. Although similar in technology the on-line UPS is more costly than the other two UPS systems, due to the fact that it has an advanced cooling system and a more powerful charger.
The standby and the line interactive UPS systems are not rated as highly as the on-line UPS system. This is due to the fact that it offers a protective electric firewall between the inward bound energy and the vulnerable equipment. If you are considering buying a UPS system, then this is a more feasible option.
