ND.. line chokes
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)
An ND.. line choke is required in the following cases:
- To limit the charging current for MDP90A-0100..
- When using MDR9.B.. supply and regenerative modules
When selecting the line choke, observe the assignment of power supply module and line choke, see chapter ND.. line choke.
