These days, the use of computers as an integral part of human life. In fact, the average person may not work well in a day without the use of a range of computer-run, and automated equipment, including the UPS, also known as continuous or uninterrupted power supply.
There are several manufacturers of UPS systems today, thanks to the fact that the demand for these products has increased significantly in recent years have shown. For this reason, it isnow some brands to choose from. You have to choose carefully, though, to get the correct UPS for your computer, so that difficulties are encountered later. There are also various types of systems examined, including the three categories, namely the on-line, line-interactive UPS and standby.
A double conversion online UPS uses the method for the adoption of AC input and the consequent adaptation of the DCThey go through the battery, then back to AC (120V in particular one) to flow to the protected equipment. On the other hand, a line-interactive UPS is in line with the drive to maintain the deformation of the lost computer battery current path away from the charging mode when the normal supply temporary power. Meanwhile, a standby mode (also known as off-line) UPS effective load input power is supplied, this means that the backup power circuitonly when the power has some difficulties or not completely known. Most users will want to stand-variety, variety or line-interactive UPS as they are known to be less of a burden on the pocket. Let us know these technologies.
The standby UPS, among others, provides the basic functions: It provides battery backup and surge protection. This type of system allows devices to be connected directly to each arrivalelectrical service, the increase is protected by a power strip, which is normally connected to the main switch. After the input voltage falls below the expected level, then the UPS is waiting on its simple internal DC / AC inverter circuit and rotate mechanically, the device switches to its DC-AC Power Inverter - all this happens in 25 milliseconds or less, depending on the time taken for the standby UPS must recognize lost power.
The line-interactive UPSworks similarly to the standby UPS, but there is an additional feature in the form of a multi-tap transformer, variable voltage auto, a particular type of electrical transformer capacity to subtract or add weight powered coil of wire, then increase or decrease the total output voltage. This species tolerates over-voltage and low voltage (continuous) are on the ground without being consumed or the battery backup that make more interruptions duringthe transfer of power to the battery.
The use of large aggregates have been linked to hand another option, namely, dynamic UPS, the use of a synchronous generator or engine on the net through a butterfly valve is known. A flywheel keeps the flow of energy and fluid regulator maintains power to the load. Other technologies are Uninterruptible Power Supplies UPS Diesel Rotary UPS and fuel cell.
