1、 The inverter power supply is converted from DC (direct current) to AC (alternating current). The UPS power supply has three modes: bypass mode, mains mode and battery mode.

2、 Generally speaking, the inverter is just a complete changer without any impurities of filtered electricity. The device that converts direct current into alternating current is called inverter

3、 The bypass mode of UPS power supply is necessary to use mains power instead of passing through the UPS power supply host. The mains power mode is that the mains power passes through the rectifier of the machine, filters the impurities in the mains power, and then passes through the inverter provided by the host to supply power to the equipment. The battery mode is that DC power (battery power) is passed through the inverter to supply power to the equipment. In this way, there will be good maintenance equipment.

4、 The functions and principles of inverter power supply and UPS power supply system are basically the same, and they can build the following two functions: 1. Obtain a way to adjust the voltage change, avoid various electrical obstacles, and obtain high-quality power supply; 2. In case of frequent failure of AC mains, it is necessary to ensure the necessary backup power supply capacity. The second difference between the two is that the UPS must be equipped with a battery pack, which has a short backup time, while the inverter power supply needs to be equipped with a battery. It is necessary to use the DC screens of all levels of voltage in the communication room, which have small capacity, and can ensure the uninterrupted network operation for a long time.
