Today’s computers have been improved with LSI (large scale integration) and with VLSI (very large scale integration) technologies. Due to this, chips contain large number of semiconductors and their interconnections. The power evaluation and rating of these memory and logic devices has minimized while the response time has improved extremely. However, regardless of these improvements, the microprocessor computers and process control systems are still extremely sensitive to power anomalies like, blackouts, brownouts, spikes and noise pulses.
Even tough electric utilities make effort to provide relatively stable and steady power, there is absolutely no guarantee of free services without problems. For this and many other similar reasons, obtaining an uninterruptible power supply or UPS power supply system is of great importance. UPS power supply system is a backup power supply system that includes a battery, which provides power in the event of a power outage. In other words, an uninterruptible power supply will keep your computer running after a power outage, allowing you to save data that is in your computer’s RAM and to shut down the computer without any problems.
When Is A UPS Power Supply Needed?
Before you decide to buy UPS, you need to analyze the utility power. If you determine that there are numerous power quality problems, then you should probably buy UPS device. UPS power supply will come in handy when switching between 2 utility feeds or when using backup generators. An uninterrupted backup power supply can be used in combination with a backup generator in order to cover power outage during transfer time.
Ways To Select And Apply A Uninterruptible Power Supply
According to IT experts, every machine that is run by a microprocessor should have a UPS power supply. When choosing the proper type of uninterruptible power supply for an application, you need to consider a number of different factors. For example, it is important to determine the application, to know the size and type of data and other elements. This way you will know what type of UPS power supply to choose. There are two types of you backup power supply, an on-line and offline UPS.
With an on-line backup power supply, a battery charger transforms alternating current into direct current and back to alternating current with the help of an inverter. Simply said, the on-line UPS system is powered by an inverter. In case of power outage, the battery immediately provides the power to the inverter. This way break in current is avoided. This is why the on-line UPS power supply is known as a reverse transfer system and is ideal when looking for a complete protection from any kind of power vacillation and possible power outages. On the other hand, an offline UPS system or a standby power supply, gets activated only when it senses a loss of power. These systems are perfect for protecting smaller computers that will not lose any data during short power outage. To sum up, on-line UPS systems are more expensive, but also provide greater protection.
