Online UPS

Online UPS: This kind of UPS keeps its inverter in working condition. It first converts the external AC power into DC power through the circuit, and then converts the DC power into a high-quality sine wave AC power output to the computer through a high-quality inverter. The main function of the on-line UPS under the power supply condition is to regulate the voltage and prevent electric wave interference; in the event of a power outage, the standby DC power supply (battery pack) is used to supply power to the inverter. Since the inverter is always working, there is no problem of switching time and it is suitable for applications where the power supply is strictly required. The main advantage of the on-line UPS is that it has a long-lasting power supply, usually a few hours, and it can be as large as a dozen hours. Its main function is to allow you to work in the event of a power failure. Due to its special function, the price is also obviously more expensive. This online UPS is more suitable for computers, transportation, banking, securities, communications, medical, industrial control and other industries, because computers in these areas generally do not allow blackouts.
