Vertiv/Emerson R48-2000e3 RECTIFIER MODULE
Product description:
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.
Product features:
1.Optimize the amount of energy delivered and reduce power consumption with over 96% efficiency.
2.Increase space for revenue generating equipment with modules that pack more power in a small space with high power density.
3.Facilitate easy maintenance, expansion and system changes with hot swappable capabilities.
4.Enjoy increased reliability and active load sharing with Digital Signal Processing (DSP) which translates into fewer components and
optimized operation.
5.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.
