5.3 AC output chokes
The ADL300 inverter can be used with standard motors or motors designed specically for use with inverters.
The latter usually have a higher isolation rating to better withstand PWM voltage Examples of reference regulations
are provided below: motors designed for use with inverters do not require any specic ltering of output from the
inverter. For standard motors, especially with long cable runs (typically over 100 m) an output choke may be necessary
to maintain the voltage waveform with the specied limits.
The range of recommended chokes are listed in the following table. The rated current of the chokes should be approx.
20% higher than that of the inverter in order to take into account additional losses due to modulation of the output
waveform.

Note! With the inverter operated at the rated current and a frequency of 50 Hz, the output chokes cause a voltage drop of approx. 2% of the output voltage.
