There are mainly the following:
(L) when the mains power is interrupted, the battery can be used to convert the DC into 220V AC through the inverter circuit to power the computer and network system, so as to ensure the normal operation of the computer and network system.
(2) it can stabilize the voltage of the mains and stabilize the voltage when the grid voltage fluctuates.
(3) it can suppress power harmonic interference, voltage instantaneous drop, high-voltage surge, voltage waveform distortion, electromagnetic interference and other power pollution of the power grid, provide power supply with stable voltage and pure waveform for computers and other equipment, and ensure the normal work and data of computers and network systems are not disturbed.
