DESCRIPTION OF THE BACK-UP’S OPERATION
GENERAL INFORMATION
The SINLINE XL 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
group of LINE-INTERACTIVE (VI)-class UPSs, which includes UPSs that
synchronise with the mains. The UPS is equipped with the CLEAR DIGITAL SINUS
(CDS) system, which 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-sine wave voltages. This system increases the reliability of the device
and guarantees stable operation of the UPS.
With the help of the Automatic Voltage Regulation (AVR) system the UPS instantly
corrects slight drops in the mains voltage to provide the receivers with appropriate
power supply conditions without tapping into the energy reserves stored in the
batteries.
The back-up also uses 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 operating mode the system filters the mains voltage to remove the noise
and distortions that may be dangerous for the receivers.
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 back-up
operation mode. In mains operation mode the shorting safeguard is provided by
a cut-out and overloads are signalled both visually and acoustically.
When the UPS is started in the back-up operation mode, a special soft start mode is
used in order to launch with high loads that draw high starting current, e.g. laser
printers.
Moreover, the DPC system enables long operation in battery mode by allowing
connection of an additional battery module and control of internal temperature by
means of an active cooling system, which is activated as necessary. This manner of
switching on the cooling reduces the amount of noise generated by the UPS.
The DPC system offers various modes of communication between the UPS and the
computer via a communication port or a special slot for the Ever management card
(HTTP, telnet, SNMP).
