The division of the ups power supply can be divided into two types: the backup type (OFF LINE) and the online type (ON LINE). From the standby time, it can be divided into standard type and long-term type.
In principle, the main difference between the online UPS and the backup UPS is that the backup UPS only regulates the mains when there is mains supply, the inverter does not work, and is in a waiting state. When the mains is abnormal, the backup The UPS will quickly switch to the inverter state, and the battery power will be inverted into AC power to continue to supply power to the load. Therefore, the backup UPS will have a conversion time when the utility power is reversed, generally less than 10ms, and the online UPS will be reversed after being turned on. The transformer is always in working state, so there is no interruption time when the mains abnormally turns the battery to discharge, that is, 0 interrupt.
