Frequency inverters have been developed for operation in industrial environments. It may be
necessary to implement an optional mains choke if required by the system and/or the application.
These chokes must be matched to the power range of the frequency inverter and the mains supply.
Benefits
Using an optional choke will
•
Minimise mains feedback and mains current surges
•
Significantly reduce the current harmonics
•
Restrict start-up and peak current
•
Reduce the apparent power and charge currents in the link circuit
•
Improve cos
φ
Application
The mains choke is implemented upstream of the frequency inverter and limits the input current to
approximately the output current level of the SK 5xxP. These mains chokes are UL certified and
should always be installed in the control cabinet due to their protection class (IP00). Optional
connection occurs with a connection cable to be supplied and with screw terminals at the mains choke
and at the frequency inverter.
