1. Brief introduction
1.1 System and model description
This Online Series is an uninterruptible power supply incorporating
double-conversion technology. It provides perfect protection
specifically for computer equipment, Communication Systems to
computerized instruments.
Its true online double-conversion design eliminates all mains power
disturbances. A rectifier converts the alternating current from the
utility power to direct current. This direct current charges the
batteries and powers the inverter. On the basis of this DC voltage,
the inverter generates a pure sinusoidal AC voltage, which is
modulated by an isolation transformer and then power the loads.
Computers and Peripherals are thus powered entirely by the UPS. In
the event of power failure, the maintenance-free batteries power the
inverter. This manual is applicable to the following models:
1) The DX 6000L is a standard model with inbuilt battery,
hereinafter called 6000L;
2) The DX 6000LXL is a long backup time model, which is able to
connect with the external battery bank, hereinafter called
6000LXL;
3) The DX 10000L is a standard model with inbuilt battery, hereinafter
called 10000L;
4) The DX 10000LXL is a long backup time model, which is able to
connect with the external battery bank, hereinafter called
10000LXL;
