Huawei WD2E3DCDU03DB is a DCDU-03 DC power distribution unit for WD2-series BBU3900/DBS3900 base station cabinets. Tech-Star (UK-based, shipped worldwide) stocks legacy Huawei base station power hardware. Enquire to confirm compatibility.

The Huawei WD2E3DCDU03DB is a Direct Current Distribution Unit of the DCDU-03 family, used within Huawei’s WD2-series BBU3900 and DBS3900 base station cabinets. The DCDU-03 provides up to nine separate -48V DC outputs from a single DC feed, using miniature circuit breakers (MCBs) to protect and distribute power to the GTMU, UPEU, RRU and other units housed in the same cabinet. Depending on its MCB configuration the DCDU-03 family is further split into DCDU-03A, DCDU-03B and DCDU-03C variants, which share the same physical appearance, engineering specification and connector layout. A built-in surge protection board guards connected equipment against transient voltage spikes, with dedicated alarm signalling back to the site monitoring system. This is a legacy base station power component used to maintain or repair the DC distribution subsystem of existing WD2-series BBU3900/DBS3900 installations. Tech-Star (UK-based, shipped worldwide) stocks legacy Huawei base station power hardware including this unit. Get in touch with your cabinet and MCB configuration details to confirm compatibility before ordering.
