Technical data for braking resistors, chokes and filters
Technical data
1-phase inverter
Use is required under the following circumstances:
• Unit load I
N
> 100 %
• Supply system inductances < 100 µH per phase
• Operation of several units that are switched simultaneously The line choke limits
overvoltages caused by the switching.
Use is optional in the following instances:
• Reduction of the supply system current harmonics
• To support overvoltage protection
Connecting sev-
eral single-phase
inverters on one
three-phase line
choke
Prerequisites for connecting several 1-phase inverters to one 3-phase line choke:
• The line contactor must be designed for the total current.
• The fuse must correspond to the nominal current of the line choke.
• The symmetric connection of the MOVITRAC
®
B to line choke.
3-phase inverters
Using line chokes is required when operating more than 5 inverters that are switched on
simultaneously. The line choke limits overvoltages caused by the switching.
Use is optional for supporting overvoltage protection.
