The 2000 watt high-efficiency eSure rectifier R48-2000e3

SKU: 12074 Category:


R48-2000e3 Overview

The 2000 watt high-efficiency eSure rectifier (model R48-2000e3) converts standard AC supply voltages into stable nominal -48 VDC voltage that is adjustable to application needs. This constant power rectifier designed with the latest patented switch-mode technology, uses DSP (Digital Signal Processing) for efficient operation.
The R48-2000e3 can be connected in parallel with other rectifiers and converters to support a variety of telecom applications. Unified remote management and control of the power system is enabled when combined with a Vertiv™ controller.


  • Optimize the amount of energy delivered and reduce power consumption with over 96% efficiency.
  • Increase space for revenue generating equipment with modules that pack more power in a small space with high power density
  • Facilitate easy maintenance, expansion and system changes with hot swappable capabilities.
  • Enjoy increased reliability and active load sharing with Digital Signal Processing (DSP) which translates into fewer components and optimized operation.
  • Appreciate the flexibility to utilize in a variety of applications with a wide input voltage range of 85 VAC to 300 VAC and full power output at temperatures from -40˚C to +65˚C.
