The unit is designed to supply a linear vacuum arc evaporator by a regulated constant current with arc spot position control. The unit includes a control system which manages two current outputs with and arc ignition system. Cathodic spot position is controlled by two sensors placed near the ends of the evaporator.

Control is carried out via the RS485 interface (ModBus RTU protocol).
