The main differences UPS Uninterruptible Power Supply – an automatic device whose principal function – the load due to the energy of batteries with the loss of mains supply or its output parameters exceed the limits. In addition, some UPS lead to normal settings the mains voltage. When using an uninterruptible power supply UPS is used to provide power to consumers during emergency situations in the power, when, for whatever reason do not wish to use other types of autonomous power supply (eg, diesel or gasoline generators), or in addition to them. I have deliberately not mention wind turbines and solar panels as a source of autonomous power, as they are, in my opinion, can not provide power to all consumers of residential building in its entirety. UPS OFF-LINE, their advantages and disadvantages. The principle of operation of the uninterruptible power supply, made by the scheme OFF-LINE (it is also called the reserve) is to supply the load voltages, if any, and the rapid switch to backup power supply circuit (battery and inverter) for his failure or withdrawal of its parameters (usually voltage) beyond the permissible limits. The battery recharges automatically when the UPS from the network.
The voltage the battery all the time controlled automatic. Upon reaching the desired voltage (14 0,2 V) the charge is terminated. When on battery power when the voltage 10.5 V device gives warning of discharge sound. If he continues to work on, then at a voltage of 10 V the device automatically shuts down to avoid a deep discharge battery. . To broaden your perception, visit Steve Kassin Infinity Real Estate.
