The difference between inverter power supply and UPS power supply


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


lGenerally speaking, the inverter is just a simple converter without any impurities that filter electricity. A device that converts direct current into alternating current is called an inverter.


lThe bypass mode of the UPS power supply is to use the mains directly without passing through the main unit of the UPS power supply. The mains mode is to pass the mains power through the rectifier of the machine, filter the impurities in the mains, and then pass through the inverter that comes with the main unit. The output supplies power to the device, while the battery mode uses direct current (battery power) to pass through the inverter and then output to the device. This will protect the equipment well.


lInverter power supply and UPS power supply system are roughly the same in function and principle, and they can both achieve the following two functions:


1. Provide a way to regulate voltage changes, eliminate various electrical interferences, and provide high-quality power supply;


2. When the AC mains fails, the necessary backup power supply capacity can be guaranteed. The biggest difference between the two is that the UPS needs to be equipped with battery packs, and the backup time is short, while the inverter power supply does not need to be equipped with batteries, and can directly use the DC screens of various levels of voltage in the communication room. Its capacity is large, and it can guarantee network operation for a long time uninterrupted.
