eSure™ Rectifier

R48-5800e​

​​
The eSure™ R48-5800e rectifier 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 rectifier designed with the lates​​t patented switch-mode technology using DSP (Digital Signaling Processor) functionality for efficient operation.

For a higher load capacity, rectifiers can be connected in parallel and intelligent control can be added with the help of a separate controller.
