Notes:
- AC Line Choke inductance values calculated @400V, 50Hz / 480V, 60Hz
- AC Line Choke impedance is nominally 3% of drive rating
- AC Line Choke maximum voltage rating should be 480V +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
Calculation
The choke ratings listed above are for guidance only. Customers may want to calculate their own ratings
