This UPS utilises an innovative charging method reserved only for the most
advanced UPSs (CBC - COOL BATTERY CHARGING) which utilises the elements of
an internal inverter. During the mains operation mode it charges the batteries and in
the back-up operation mode it converts the internal energy of the battery into the
alternating current to power the protected devices.
MAINS OPERATION MODE
Connecting the UPS to the mains does not cause current to appear at the back-up's
output. UPS batteries are not charged either. The UPS is turned on upon pressing
the power switch on the front panel. Switching on is accompanied by the operation
mode LED lighting in red and then (after approximately 3 seconds) a sound signal.
Subsequently all LEDs on the front panel light up so their correct operation can be
verified (autotest).
Next, the UPS will attempt synchronisation with the mains. If the mains voltage of the
socket to which the back-up's power cord is connected is appropriate, then after
approximately 5 seconds the UPS switches to the mains operation mode and lights
the green operation mode LED. If the mains voltage is incorrect (too low or too high
voltage or frequency exceeding the operation range) the UPS switches to the back-
up operation mode and lights the red operation mode LED.
In the mains operation mode the UPS's outlet provides mains voltage that was
filtered and optionally raised by the AVR system.
BACK-UP (BATTERY) OPERATION MODE
In the back-up operation mode the true sine wave voltage output is generated by the
battery until the mains voltage returns, the battery is discharged or an emergency
situation takes place. When operating in the back-up mode, if the batteries are
discharged or the appropriate command from the control software is given, the UPS
may switch to the battery stand-by mode.
