2. Product description
The CX1-3KVA series UPS 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 disturbance. A rectifier converts the alternating current
from the socket outlet to direct current. This direct current charges the batteries and powers the inverter. On the basis of
this DC voltage, 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, communications, government, traffic, manufacture, education and so on.
2.1 System type and configuration
According to the different configurations of the parts of the battery in the machine, CX series UPS can be divided
into two categories: standard type and long backup time type; According to different power points, it divided into: 1KVA,
2KVA and 3KVA.
