Huawei R4875G5 4000W 48V 1U Rectifier Module

The Huawei R4875G5 is a high-density 4000W rectifier module for telecom and industrial DC power systems. It converts a wide AC input range into a regulated 48V-class DC supply for compatible Huawei embedded power platforms.

The module accepts 85–300V AC at 45–66Hz and delivers 42–58V DC, with 53.5V or 57V nominal output settings. Full 4000W output is available from 176–300V AC, while peak conversion efficiency reaches 97% and the input power factor is at least 0.99 under specified load conditions.

Hot-swap support, digital control, CAN communication and forced-air cooling simplify integration and service. The compact 40.8 x 105 x 269mm module weighs no more than 2.2kg and operates across a -40°C to 75°C temperature range.
