Lithium ion battery UPS power is generally composed of rectifiers, force batteries, inverters, static switches and control systems. Usually used in line UPS power supply. The UPS power battery first turns the power supply of the electricity input into a regulated DC power supply, supplies lithium ion batteries and inverters, and then re-turned to stable, pure, high-quality AC power.

It fully eliminates any power problems that may occur in the input power supply, such as voltage fluctuations, frequency fluctuations, harmonic distortion, etc. Lithium-ion battery UPS power supply is a constant voltage containing the energy storage device, with a constant voltage, constant frequency of constant frequencies in the inverter. When the main electricity is normal, the UPS power supply will use the mainstay of electricity or regulatory, and the battery is used to charge the battery.

At the same time, the battery is charged; when the electricity is interrupted, the UPS immediately within 4-10 milliseconds or zero interruption The power supply of the lithium ion battery continuously supplies electricity to the load by inverting conversion, so that the load maintains normal operation to save the data and protect the loaded hardware and hardware is not damaged. As in principle, the UPS power battery is a set of digital and analog circuits, automatic control of the power electronic device integrating inverter and maintenance storage unit; functionally, lithium ion battery UPS can be abnormal in the city Effectively purify the city's electricity; can also continue to supply power to the computer when the city is suddenly interrupted, so that you can have sufficient time; from the use, with the advent of information society, UPS power supply It is widely used in all aspects of information acquisition, transmission, resolution, storage to the use of all aspects, which is increasing as the information use is increasing. Lithium-ion battery UPS power maintenance skills: 1 When the UPS power battery system fails, it should first identify the original, the division is the load or the UPS power system; is the host or battery pack.

Although the lithium-ion battery UPS host has failed self-inspection function, it is opposite, it is very convenient to replace the accessories, but to repair the fault point, still need a lot of decomposition, testing work. In addition, if the self-test portion has failed, the displayed fault content may be wrong. 2 When the battery is discovered in the UPS battery pack, the battery should be recovered and repaired in time, and the corresponding approach to restore and repair should be used in time, which can be replaced without recovering and repairing, but different capacities cannot be replaced.

Different performance, different manufacturers of batteries, otherwise it may have adverse effects on the entire set of batteries. 3 The wind in the machine will deposit the dust in the machine. When the air is wet, the host control disorder causes the host's working abnormality, and there is an inaccurate alarm, and a large amount of dust will cause the device to heat dissipation.

Generally, it should be thoroughly cleaned every quarter. Secondly, when dust removal, check the connections and coupons have no looseness and contact.
