A large number of control units are available enabling the operation of lifting and adjustment systems as well as telescopic columns. These have either an alternating current (100 or 240 V) or a direct current connection.
Some control units can control only a single actuator, while others are designed to connect up to 6 actuators and multiple external Human Machine Interfaces (HMIs). There is also a control unit for DC actuators with battery operation (charging via a power cable).
These are fail-safe and medically approved.
