Power supplies, which feed magnetic systems of electron linac, together with the control system are very critical parts of any linac. The quality of power supplies and control software define s safety of the accelerator operation, stability and cost of operation. One of the today’s tendencies in power supply system architecture is to use distributed CAN-connected power supplies with high level of local intellectual properties. These properties allow to achieve high stability, high safety of operation together with the sp ecific features such as coil temperature check without any temperature sensors. Such programmable power supplies with the intellectual CAN- bus/CANopen controller have been designed for the specific accelerator applica tions. The control system software was adapted to operate with CANopen protocol. “Marathon IPP-1/100” and “Marathon IPP-4/35” power supplies with CANopen are used now within the control systems of LU-60m and LU-10 linacs. 3200 hours of continues operation were achieved since the year 2008.
