DC Power for Business-Critical Continuity™ eSure™ Rectifier R4811600, R4812000e and R4812000Le Key Features High-efficiency rectifier designed for -48V DC power applications Optimized depth – small footprint allows installation in short-depth racks and cabinets DSP (Digital Signaling Processor) – means fewer components, optimized operation and active load sharing for increased reliability Compliant with global standards – delivers quality, performance and reliability no matter what the application or location demands In addition to reducing power consumption and lowering operating cost, eSure™ high-efficiency rectifiers offer superior performance and uncompromised reliability. Description High-efficiency eSure™ rectifiers R48-11600, R48-12000e and R48-12000Le are designed to convert standard AC supply voltages into stable nominal -48V DC voltage that is adjustable to application needs. These rectifiers are constant power rectifiers 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. High efficiency,reduces power consumption for lower operating costs,see diagram.
