AAC: What is Adaptive Acceleration Control?
AAC is the next evolution in soft starter technology.
Using AAC, the soft starter learns your motor’s performance during
start and stop, then adjusts control to optimize performance.
The soft starter estimates the motor’s speed throughout each
AAC start and stop, and adjusts power to the motor to provide the
selected acceleration or deceleration profile.
AAC is largely unaffected by changes in load, and is particularly
suitable for pumping situations.
AAC offers three starting and stopping profiles: early, constant and
late acceleration/deceleration.
AAC is only available on MCD 500 soft starters.
