Many face difficulties when choosing the uninterruptible power supply unit. At the same time it is necessary to consider not only the cost, conveniences of use and appearance of the device, but also and its parameters, to high-quality and harmonious work.
What UPS to choose for the computer?
Before the choice of the UPS it is necessary to be defined for what equipment it will intend. Also it is necessary to know what volume of the electric power will be consumed. To learn an electric power expense, just it is necessary to read characteristics of the device. If you do not know the UPS for the computer how to choose, then it is possible just to go online and find your model of the computer. There all data will be provided.
The ordinary personal computer consumes standard amount of energy – 362 W. From total number of 300 W it is spent for operation of the system unit, 45 W are consumed the monitor and 17 W leave on the modem. The power unit of measure in the UPS makes volt-ampere and therefore it is necessary not to forget to transfer indicators of power of the equipment to W. For this purpose it is necessary to increase an indicator by coefficient equal 0.6. Here so the uninterruptible power supply unit with a power of 700 VA will be able to serve the device which consumes no more than 420 W.
The choice of the UPS for a gas copper
If you do not know how to choose the UPS for a gas copper then it is necessary to consider that they differ from the UPS for computers. Such power supplies have to have a number of positive properties which are distinguished with various characteristics of loading. They are obliged to have the output direction in a sinusoidal form in order that the transformer, the electric motor and valves could work in the normal mode. Also the device has to have the big duration of work at the autonomous mode, that is during the work from the accumulator, till 8 o'clock. Coppers can be sensitive to phase tension. The UPS in operating time from the accumulator has to have the same phase of output voltage, as well as in network.
