The Huawei AIU03-100C (Part Number: 02312MUD) is a carrier-grade AC Input Unit power distribution module engineered for high-capacity telecom DC power systems (such as TP482000B and ETP48400), featuring heavy-duty busbar blind-mate connectors and comprehensive input protection.
Need to confirm a model, specification, or project configuration? Our team can follow up by email or phone.
This unit serves as the primary AC ingress power distribution interface in large Huawei telecom power cabinets, distributing utility or generator AC power directly to the rectifier subrack backplane while providing over-current isolation and energy sampling.
Eliminates complex external cabling, prevents busbar overheating through low-impedance gold-plated contacts, and enables hot-swap maintenance without powering down the entire telecom power cabinet.
Engineered for telecom switching centers, 5G core network facilities, modular IDC energy rooms, and maintenance/expansion of Huawei TP482000B and ETP48400 power systems.
