11. AC line reactor (Line choke)
A 3-phase AC line reactor must be used to comply with the harmonic current limits required by
the EN 61000-3-12 standard.
Note: A DC reactor is integrated inside all ADrive models.

Note: It is recommended to use AC line reactors with impedance values 3% (Z%) for standard
applications. The impedance value %Z is also the voltage value that drops across the AC line
reactor (for example: 5% voltage drops across the AC line reactor with impedance value 5%).
5% reactor would be a better choice for reducing the harmonic currents with a balanced mains
supply (less than 5% voltage imbalance between phases).
It is suggested that a 3-phase AC line reactor be installed on the supply line also to obtain the
following benefits:
- limiting the input current peaks on the input circuit of the inverter
- increasing the duration of line capacitors inside the inverter
- increasing power factor, thus reducing line current
