The input rectifier converts the alternating mains current to a direct current. The
power factor correction system used in the rectifier enables significant elimination of
noise transferred to the power system. The direct current bus is the main source of
power of the inverter which produces sine alternating current that powers the
receivers. An internal charger is responsible for charging the accumulator; it has
a very low alternating charging current component, which significantly extends
accumulator life. The microchip control system ensures precise and reliable
operating of the whole power supply system.
The automatic bypass system increases the safety of the whole system. If the
tolerance limits for the parameters of the inverter are exceeded, the mains current is
provided to the load directly. This way the automatic bypass system constitutes an
additional, passive safeguard of connected load. The additional function of manual
engaging of the bypass enables complete powering of load from the mains. This way
it is possible to supply power to the load from the mains without any involvement of
the battery back-up’s internal functional units.
