The PARC 120-20/3 power supply is intended for power supply and control of the PARC 49 or PARC 29/3 impulse electric arc evaporator. The difference between the PARC120-20/3M power supply and PARC 120-20/3 is in the presence of a system that provides synchronization of the power supply with the same type of power supply in the master or slave mode, as well as with the power supply for the electrical bias of the BPS 150-30P120 substrates and switch control channels electromagnetic system for deflecting the flow of carbon plasma DCC3000. The main technical characteristics of the power supply correspond to those of PARC 120-20/3.
