[The pulse arc evaporator](https://vaclab.ru/devices/arc_evaporators/pulsed_arc_source) is designed to generate a flow of carbon plasma which is condensed on a substrate. The cathode material evaporates in the cathode spot of the pulse vacuum arc, burning on the end surface of the cathode. Due to the action of the magnetic field of the flowing current, the carbon plasma is accelerated towards the substrate, providing a high hardness of the coating.

[The unit](https://vaclab.ru/power_sources/arc_evaporators_power_supplies/pulsed_arc_evaporator_ps) is designed for charging a capacitive storage device and initiating the discharge of a pulsed arc evaporator. The adjustable charging voltage is 0..350 V, pulse frequency 1..25 Hz Control is carried out via the RS485 interface (ModBus RTU protocol).
