DESCRIPTION OF THE UPS'S OPERATION

GENERAL INFORMATION

The SINLINE UPS is a state-of-the-art electronic device constituting an autonomous
source of true sine wave voltage of ~230V. This device belongs to the LINE –
INTERACTIVE class of uninterruptible power supply devices, including the CLEAR
DIGITAL SINUS (CDS) system that generates a clear voltage sinus at the battery
output. This system increases the reliability of the device and guarantees a stable
operation of the UPS.
The UPS also utilises the system of advanced DIGITAL POWER CONTROL (DPC)
which precisely shapes the oscillation of the output voltage to obtain a clear sinus. In
the mains operation mode the system filters the mains voltage to remove the noise
and distortions that may be dangerous for the load.
With the help of the Automatic Voltage Regulation (AVR) system the UPS instantly
corrects slight drops in mains voltage to provide the receivers with appropriate power
supply conditions without tapping into the energy reserves stored in the batteries. In
the battery module operation mode the system generates a precisely stabilised
output voltage in the shape of sinusoid, which enables supplying power to a wide
range of equipment that does not tolerate quasi-true sine waves.
The dedicated DPC system monitors the operation of the UPS; it has a precise and
very quick-reacting system of detecting overloads and outlet shorting in the battery
module operation mode. In the mains operation mode the shorting protection is
provided by a circuit breaker, while the overload protection provided by the DPC
system is as precise, as it is in the battery module operation mode.
When the UPS is launched in the battery module operation mode, the DPC system
utilises a special soft start mode in order to engage with high loads that draw high
starting current.
The DPC system also provides advanced methods of communication between the
UPS and the computer via the RS232 port.
The DPC system provides precise measurements of such basic parameters of the
UPS as: battery voltage, mains frequency and input voltage, voltage and output
current of the battery module, the power of load connected.
