The eSure™ R48-3500e high-efficiency rectifier is designed to convert standard AC supply voltages into stable nominal -48V DC voltage that is adjustable to application needs. The R48-3500e is a constant power rectifier designed with the latest patented
switchmode 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.
Features
1.3500 Watt high-efficiency rectifier designed for -48V DC power applications.
2. Optimized depth – reduced footprint allows installation in short-depth racks and cabinets.
3. DSP (Digital Signaling Processor) – means fewer components. optimized operation and active load sharing for increased reliability.
4. Compliant with global standards – delivers quality, performance and reliability no matter what the application or location demands.
5. High efficiency, approaching 97% – reduces power consumption for lower operating costs.
6. Hot pluggable – facilitates future extensions.
