protection / class D) and mains energy backfeed
protection
♦ Rectifier section with PFC logic
(power factor correction unit)
♦ Separate battery charger with
switch mode power supply technology
♦ IGBT inverter for continuous supply of connected loads
with sinusoidal AC voltage
♦ Automatic electronic bypass (SBS)
as additional, passive redundancy
SBS = S
