ND.. line choke
The ND.. line chokes can be used optionally:
- 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)
Connect a line choke for limiting the inrush current:
- with 5 or more 3-phase devices
- with 2 or more 1-phase devices
- for each inverter MCX91A-0110-2E1-4-..
