- Adaptive control – the latest soft start technology. The RZ3 constantly monitors the motor’s performance and adjusts the power to deliver your desired acceleration or deceleration profile.
- Traditional current limit soft starting limits peak current in generator set applications.
- Current ramp starting is ideal where the load can vary between starts.
- Kickstart option for loads needing high breakaway torque.
