Apno's on line UPS power supply is always powered by power supplies that are converted to zero after a power outage, and then the power supply is powered by a 0.04 second conversion period after power down.
The online type does not require conversion time, just as batteries do, even if the mains power is disconnected.Backup, online interactive, is about to be eliminated.
Backup power supply: when the city power is in normal supply, the mains supplies power directly to the load through the AC bypass channel and then through the change-over switch without passing through the UPS power supply. The inverter in the machine is in a stopped state, and the UPS power supply at this time is essentially equivalent to a general performance voltage regulator. In addition to improving the voltage fluctuation of the mains voltage, there is little improvement in the frequency instability of the voltage, the distortion of the waveform and the interference from the grid intrusion. Only when the mains power supply is interrupted or less than 170V, the battery can supply power to the UPS inverter and supply the stabilized and square wave AC power supply to the load. As can be seen, on the principle of power supply and voltage stabilized frequency, the quality of on-line UPS power supply is obviously better than the reserve UPS power supply. Because it can realize the stable frequency and voltage supply of the load, and the switching time from the mains power supply to the storage battery, the conversion time is zero.
On line UPS, under normal circumstances, whether there is no electricity, it is composed of UPS inverter power supply power to load, so as to avoid all the municipal power grid voltage fluctuations and the impact of interference. Because the on-line UPS power supply can realize the steady frequency and the stable voltage supply to the load, and when the power supply converts from the city electricity to the storage battery power supply, its conversion time is zero. Truly provide users with high quality voltage regulator, frequency stability of pure sine wave power supply, so as to provide the power supply protection in line with the network system needs.
Online does not require switching time, and the battery, disconnect the power, even if nothing, then the preparation type conversion events, about 4~10 MS, the backup is not suitable for the general user workstation, but is available.
