Technical Specifications
AC Line Choke
Frame G, H, J drives MUST use an AC Line Choke. However, where a drive is individually supplied from a dedicated
transformer with the required impedance, the AC Line Choke is not required.
Where a system comprises a number of Frame G, H and J drives connected to a common supply, a separate AC Line Choke is
required in the supply to each drive.
When an EMC external ac supply filter is used, the AC Line Choke must be fitted between the filter and the drive.
Failure to provide the correct line impedance will severely reduce the drives lifetime and could result in catastrophic
The required AC Line Choke line impedance is nominally 3% of the drive rating.
Parker Hannifin Manufacturing can supply the following ac line chokes:
