Product Overview
The R4850G2 delivers a maximum output power of 3000 W at 176-290 VAC input, providing a regulated 42-58 VDC output with a 53.5 V default setting for -48 VDC telecom equipment. The module draws up to 17 A from an 85-300 VAC wide-range input across 45-66 Hz, with input power factor >= 0.99 and THD <= 5% for clean grid interaction.
Peak efficiency is specified at >= 96%, and the module operates from -40 to +75 degC, making it suitable for outdoor cabinets and unconditioned equipment rooms. The compact 40.8 x 105 x 281 mm module weighs no more than 2 kg, matching standard Huawei rectifier slots.
CAN bus communication reports status and alarms to the Huawei system controller, and the hot-swappable design allows replacement or capacity growth without interrupting the load. The module is certified to TUV, CE and UL/CB requirements and is RoHS compliant.
