The arc evaporator ([D40 ](https://vaclab.ru/devices/arc_evaporators/arc_evaporator_40mm)and [D80](https://vaclab.ru/devices/arc_evaporators/arc_evaporator_80mm)) is designed for coating by vacuum arc evaporation. 
The cathode material evaporates in the cathode spot of the vacuum arc burning at the end surface of the cathode. 
Stabilization of the position of the arc spot and focusing is provided by means of magnetic coils. 
The evaporator makes it possible to apply coatings from various metals, including refractory ones, as well as their compounds - nitrides, carbonitrides, oxides.

The [unit ](https://vaclab.ru/power_sources/arc_evaporators_power_supplies/arc_evaporator_power_supply)is designed to supply two arc evaporators with regulated direct current. 
The unit includes a control and monitoring system providing control of two current channels with arc ignition systems and two evaporator coil control units.

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