Modulating actuators ASR

A compact design due to the patented ellipto-centric gearing and a backlash-free torque sensor:
These are the advantages of the part-turn actuators ASR.

The VARIOMATIC controls are always included, either as integrated version or on a wall bracket. On request also available with bus connection.
