2. Introduction
Congratulations on your choice of the uninterruptible power system (UPS), the UPS comes in
nominal power ratings of 1000VA, 2000VA and 3000VA. It is designed to provide conditioned
power to microcomputers and other sensitive electronic equipment.
When it is generated, alternating current is clean and stable. However, during transmission and
distribution it may be subject to voltage sags, spikes and complete power failure that may
interrupt computer operations, cause data loss and even damage equipment. The UPS
protects equipment from these disturbances.
The UPS is a compact, on-line UPS. An on-line UPS continuously conditions and regulates its
output voltage, whether utility power is present or not. It supplies connected equipment with
clean sine-wave power. Sensitive electronic equipment operates best from sine-wave power.
For ease of use, the UPS features a LCD display to indicate all information for UPS, and
provide kinds of function buttons.
