In the UPS uninterruptible power supply, what is the difference between the bypass power and the city power?
UPS uninterruptible power supply, including static bypass and maintenance bypass in two, which is the internal static bypass through the UPS line, the conduction process of UPS is running and maintenance bypass is completely off UPS internal devices, maintenance bypass conduction
UPS can be shutdown, maintenance and other activities, the two bypass and city power is essentially different, that is, the city power in the UPS back-end load power supply,
The UPS should try to avoid bypassing, because in this state it must be that the UPS is not normally powered by rectification and inverting to the back load
