AC30 series Variable Speed Inverter
AC Line Chokes (optional)
AC30 frames K - N have an internal DC link choke. However, in some instances an external AC line choke may also be required.
1. Frame K: when used on supplies delivering more than 18kA but less than 100kA RMS symmetrical Amperes, 480V maximum.
2. Frames L, M & N: when used on supplies delivering more than 65kA but less than 100kA RMS symmetrical Amperes, 480V
maximum.
3. when used to mitigate supply quality issues.

Notes:
1. Number of supply phases: 3.
2. Supply voltage rating: 480V +10% max IT/TN.
3. Required AC line choke impedance is nominally 3% of the drive rating.
4. Frequency of operation: 50 – 60Hz.
5. Choke inductance during HD overload should be a minimum of 90% nominal inductance.
6. Typical AC line choke harmonic current content:
