The eSure™ R48-5800e rectier converts 260 to 530Vac 3-phase AC supply voltages
into stable nominal-48V DC voltage adjustable to the needs of the application. The
R48-5800e is a constant power rectier designed with the latest patented switch-
mode technology using DSP (Digital Signaling Processor) functionality for efcient
operation.
For a higher load capacity, rectiers can be connected in parallel and intelligent
control can be added with the help of a separate controller.
