1. Brief introduction
1.1 System and model description
The On-Line-Series is an uninterruptible power supply incorporating double-converter technology. It provides perfect protection specifically
for strict load. The double-converter principle eliminates all mains power disturbances. A rectifier converts the alternating current from the
socket outlet to direct current. This direct current charges the batteries and powers the inverter. In the event of power failure, the
maintenance-free batteries power the inverter. Thus the inverter generates a sine wave AC power, which permanently supplies the loads.
Designed with the proven on-line, double conversion architecture, this series of UPS offers the greatest degree of availability in power
protection and provides continuous high-quality AC power to connect strict load, especially for the basic equipments in some areas as:
finance, communication, government, traffic, manufacture, education and so on.
