Huawei TN51PDU02 TN51PDU02 Power Supply

The Huawei TN51PDU02 is a DC Power Distribution Unit board used in the Huawei OptiX OSN 8800 series optical transmission platform, part of the wider OptiX OSN family of SDH/OTN/WDM transport systems deployed in metro and long-haul carrier networks. The PDU board sits in the overhead cabling area of the OSN 8800 subrack and distributes incoming -48V DC input power to the subsystems and boards within the chassis, protecting each downstream feed with dedicated circuit breakers rated for the subrack’s power budget (the PDU family in this range is commonly specified with a 60A breaker capacity). By centralising power distribution and protection at the subrack level, the PDU02 board simplifies fault isolation, since an individual circuit breaker trip on the unit identifies a specific downstream fault without taking down the whole shelf. It is a field-replaceable unit intended for engineers maintaining or expanding OSN 8800 platforms, and is commonly sourced as a refurbished or pulled unit when replacing a faulty power feed or provisioning additional subracks. Tech-Star (UK-based, shipped worldwide) supplies tested Huawei OptiX parts including power distribution units, control boards and interface cards; get in touch with our engineers to check compatibility with your specific OSN 8800 configuration before ordering.
