Motor control: Control unit synchronizes 6 actuators


SKF introduced what they call "Smart Control Units" (SCUs) that can synchronize the speeds of up to six actuators and store frequently used positions for quick selection using one command. These units feature a standardized plug system (DIN8 for actuators and HD15 for operating devices), three or six channels for actuators, and adjustable operating parameters. All promote customization to satisfy a wide range of medical and industrial applications.

A single fault safety is standard with all three versions (24 V dc, 120 V ac, and 230 V ac), which interrupts or prevents movement of all actuators upon detection of electrical failures of internal and connected hardware. The unit's transformer protects against overload with a specialized thermal shield. Routine safety checks by the unit contribute more safeguards. The units are manufactured in accordance with EN60601-1 and UL60601-1.

SCUs feature built-in power supplies and connections for hand switches, foot switches, and desk switches. Integrated inputs can connect up to four external limit switches for multi-purpose functionality. A security cover protects the internals against outside influences or accidental plug pulling.

Optional external storage batteries can be connected by cable to enable flexible positioning. A battery charger inside the housing eliminates any need to adapt the SCU, regardless of battery type.

SCUs are compact and lightweight (ranging from 1.2-3.8 kg, depending on model). Specially customized control unit solutions can be engineered.
