2.2 System description
The UPS is connected to a safety socket between the public
mains and the electrical loads to be protected. During normal
operating conditions when the Protect B.
PRO is being supplied
with mains voltage, the battery charge rectifier keeps the battery
fully charged.
Electrical loads connected to the Protect
B. PRO are supplied
with power via mains filters in this operating condition. These
filters provide effective protection against mains overvoltage
spikes and high-frequency interference.
