System Description
The UPS runs in continuous operation according to the double converter princi-
ple. It serves for the processing of the mains current and provides an uninterrup-
tible and interference-free one-phase voltage for operations critical appliances.
In addition to providing power to the appliance, it also maintains the internal ac-
cumulators in charged condition. In the case of a mains failure or interference,
the UPS continues to provide a clean supply voltage from the UPS-output with-
out interruption. During the backup mode, power is provided from the accumula-
tors.
