5.7. CHOKES / FILTERS
NOTE! A three-phase inductance should be connected on the AC Input side in order to limit the
input RMS current of AVy series Drives. The inductance can be provided by an AC Input
choke or an AC Input transformer.
In the case of DC power supply, from size AVy4185 insertion of an AC mains inductance
on the power supply input of the power supply unit is compulsory (for the type of
inductance, consult the manual of the power supply unit), see figure 5.5.1.2.
NOTE! For the use of output sinusoidal filters, please contact the nearest Gefran office.

For all the sizes the input choke is strongly reccomended in order to:
- prolong the life time of the DC link capacitors and the reliability of the input rectifier.
- reduce the AC mains harmonic distortion
- reduce the problems due to a low impedence AC mains (≤ 1%).
NOTE! The current rating of these inductances (reactors) is based on nominal current of standard
motors, listed in table 3.3.3.1 in section 3.4.4, “AC Output”.
5.7.2. Output Chokes
The AVy Drive can be used with general purpose standard motors or with motors specially designed for
Drive use. The latter usually have a higher isolation rating to better withstand PWM voltage.
