The power supply unit is designed to operate as part of a pulsed electric arc source of carbon plasma with initiation of a vacuum arc discharge by a laser pulse. The power source is used to charge an energy storage unit with a capacity of 2 000 μF to a preset charging voltage and synchronize the operation of one solid-state laser for initiating an arc discharge. Specifications match those of PARC 100-120L.

The difference between the power supply consists in the presence of a system that provides synchronization of the operation of the source with the same type of power supply in the mode of the master or slave device, as well as the power supply for the electrical bias of the BPS 150-30P120 substrates..
