Description

Line chokes are used:

  • To support overvoltage protection
  • To smoothen the line current, to reduce harmonics
  • For protection in the event of distorted line voltage
  • To limit the charging current when several inverters are connected together in parallel on the input end with a shared line contactor (nominal current of line choke = total of inverter currents)
    • With 5 or more 3-phase devices
    • With 2 or more 1-phase devices

Using a line choke per inverter is mandatory with MCX91A-0110-2E1-4-..
