GENERAL FEATURES OF THE UPS UNIT
The POWERLINE 31 UPS systems consist of the following functional blocks:

system of rectifiers with PFC (power factor correction)

battery charger,

battery set,

frequency converter produced in high frequency IGBT technology,

automated by-pass system (static BYPASS),

manual (service) bypass system,

microprocessor-based control system with measurement circuits,
Upon converting AC power (from the three-phase mains), the input rectifier supplies
the unit's internal direct current bus. The applied power factor correction system
allows to radically reduce the consumption of reactive power from the mains. The DC
voltage bus is the basic source of power for the inverter system which in turns
generates single-phase, sinusoidal AC voltage with model parameters to be used to
power the loads. Batteries are charged with an independently operating charger. The
charging power has a very low variable component, translating into extended battery
life. The microprocessor-based control system ensures precision and reliability of the
entire power supply system.
The automated bypass system helps to increase the overall operating security of the
entire system. In case of the failure of the inverter, the power from mains is supplied
directly to the receivers. In this way the automated by-pass system works as an
additional passive protection of the load.
The additional manual bypass allows switching over completely to supplying power to
the connected loads from the mains only. That way, maintenance and service works
can be completed conveniently.
