Energy is divided into traditional energy industries such as coal, oil and gas, and electricity, and new energy industries such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy, and nuclear fusion energy. However, whether it is traditional energy or new energy, the objects of power protection are energy offices and energy equipment. UPS can ensure sufficient backup time to ensure that important load equipment will not stop operating due to failures of batteries, internal module systems, etc. In addition, UPS also plays a role in supporting the normal operation of important loads within a certain period of time to avoid accidents such as loss of data information and loss of control of the production process.
