Description
An ND.. line choke can be used as an option:
- To support overvoltage protection
- To smoothen the line current, to reduce harmonics
- For protection in the event of distorted line voltage
- Limiting 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)
Connect a line choke for limiting the inrush current:
- With 5 or more 3-phase devices
- With 2 or more 1-phase devices
