The Delta ESR-4856B C is a high-frequency communication power module featuring hot-swappable design, high efficiency, and reliable wide-temperature operation, suitable for DC power supply in base stations and equipment rooms.
The ESR-4856B C is Delta's new generation high-frequency, high-efficiency digital communication rectifier module, part of the SMR series of high-efficiency switching rectifiers. Specifically designed for -48V communication DC power systems, it is compatible with standard 1U communication power cabinets such as the MCS3000D-5, serving as a key high-power rectifier unit for wireless base stations, data centers, and core communication rooms.
Featuring fully digital control, constant power output, and hot-swappable architecture, the module supports both indoor and outdoor wide-temperature environments. With a rated output power of 2880W per unit, it offers high power density and convenient maintenance, meeting the expansion and redundancy requirements of medium to large-scale communication power systems.
