Notes:
- AC Line Choke inductance values calculated @230V, 60Hz
- AC Line Choke impedance is nominally 3% of drive rating
- AC Line Choke maximum voltage rating should be 240V +10%, TN/IT
- AC Line Choke frequency of operation is 50 – 60Hz
- AC Line Choke inductance during 150% overload operation should be >90% of its nominal value
