The modernization project of the low-current power supply system of Kurchatov Synchrotron Radiation Source has been designed and is under implementation now. It includes transition to the new power suppliers to feed electron beam orbit correctors and focusing lenses. Multi-level control system, based on CAN/CANopen fieldbus, has been developed for specific accelerator applications, which allows startup and continuous run of hundreds of power supplies together with the other subsystems of the accelerator. The power sources data and status are collected into the archive with the Citect SCADA 7.2 Server SCADA Historian Server. The following operational parameters of the system are expected: current control resolution - 0.05% of IMAX; current stability - 5*10^-4 ; 10 hours current variance - 100 ppm of IMAX ; temperature drift - 40ppm/K of IMAX.
