Mains Reactor

 

A mains reactor must be used under the following conditions:

oOperation via supply mains with low impedance (short-circuit current of supply mains greater than specified in chapter Technical Data.

oIf the nominal power of the drive is insufficient without mains reactor.

oIn the case of operation with supply mains with reactive power compensation systems.

oFor improvement of the power factor at the mains input and for reduction of mains harmonics.

A single mains reactor can be used for multiple devices. Use a mains reactor with a properly rated current.

Low-impedance supply mains cause high harmonic currents at the mains input. High harmonic currents result in considerable load on the DC bus capacitors. The load on the DC bus capacitors has a decisive impact on the service life of the devices.
