Huawei R4875 4000W 1U Rectifier Module 02312NFE-002

The Huawei R4875G5 is a high-efficiency 4000 W rectifier module designed to convert AC input power into regulated DC power for compatible telecommunications and network power systems. Its compact 1U format, wide input-voltage range and hot-swappable construction make it suitable for maintaining or expanding supported Huawei DC power installations.

Reliable Power Conversion

The module provides an adjustable 4258 V DC output, with rated output-voltage options of 53.5 V DC and 57 V DC. It delivers up to 4000 W when operated from a 176300 V AC supply, while supporting linear power derating at lower input voltages.

High-Efficiency Operation

With peak conversion efficiency of approximately 97%, the R4875G5 helps reduce conversion losses and unwanted heat in continuously operating power systems. A power factor of at least 0.97 under specified load conditions supports efficient use of the incoming AC supply.

Designed for Managed Power Systems

Digital control supports accurate voltage regulation, current adjustment and current sharing when the module is installed in a compatible managed power system. CAN bus communication enables operating information and alarms to be communicated to the supporting monitoring module.

Service-Friendly 1U Design

The hot-swappable format allows an installed module to be removed or replaced without shutting down a correctly configured redundant power system. Front-panel LED indicators provide a clear view of power, alarm and fault conditions for easier system inspection and maintenance.
