Line chokes
The following characteristics are based on the use of line chokes for the overall sys-
tem:
•
Reduction of harmonic distortions in the power supply
•
To support overvoltage protection
•
To smoothen the line current, to reduce harmonics
•
Protection in the event of distorted line voltage
•
To limit the charging current when several inverters are connected together in par-
allel on the input end with a shared line contactor (nominal current of line choke =
total of inverter currents)
The following units are equipped with a DC choke and thus do not necessarily need
an external choke:
•
240 V, BG 5 – 7
•
480 V, BG 5 – 7
INFORMATION
600 V units do not have a built-in choke
