Then PAC-3200 is designed to control two linear motors at the same time. It is intended to be used to lift heavier trunk lids and toppers/tonneau covers that require more than one motor. The PAC-3200 has a safety auto reverse feature that will stop downward travel if something would block the trunk lid. If too much current draw is detected, indicating a blocked condition, the motors will reverse and return to the previous position before they started moving down. The system can learn three user programmable heights, so the trunk/cover will automatically move to a desired position with the push of a button. There is also an auto move to position feature that will open the trunk/cover when the key is turned off and close the cover when the key is turned on.
