Huawei R4830G Rectifier (53.5VDC, 1600W, 30A)

The Huawei R4830G is a modern, digital telecommunications rectifier designed for use in 48 V DC power systems. The device converts an AC input voltage range of 85–300 V into a stabilized 53.5 VDC output, ensuring high energy efficiency, reliability, and advanced monitoring and protection functions. Thanks to its compact design, high power density, and ability to operate across a wide temperature range, the R4830G is widely used in base stations, data centers, telecommunications networks, and industrial backup power systems.

The rectifier uses digital control and intelligent monitoring technologies, enabling real-time tracking of operating parameters and communication with a supervisory system via a CAN bus. The Hot-Swap function allows module replacement during operation without shutting down the system, significantly increasing infrastructure availability.

Key features include efficiency exceeding 96%, power factor ≥0.99, and low total harmonic distortion (THD ≤5%), resulting in efficient energy usage and reduced operating costs. The rectifier supports output voltage and current adjustment and offers a full set of protection features for both the device and connected loads.
