Each Lifting Column contains an individual motorized lift mechanism.
The Control Box contains a power transformer. This converts high-voltage AC current from the wall outlet (120v) to low-voltage 18v DC current, which powers the Lifting Column.
Only the main power cable carries high voltage. All other cables are low voltage.
The Control Box contains a computer processor with embedded software controllers.
The Control Box controls all aspects of Desk motion.
The Control Box will shut down the entire Desk if a collision is detected.
The Controller is the user interface to the Desk, and directs all Desk movements by lifting or pressing down until the desired height is reached.
Preset data is stored in the Controller itself, not the Control Box.
