Huawei Rectifier EPS-01A
The Huawei Rectifier EPS-01A (also referenced as the EPS01A-N01A1) is an integrated DC power distribution and subrack system used in Huawei’s wireless and access network cabinets, such as the APM30H. It serves as the physical housing and electrical interface for power conversion modules.
Technical Description for Huawei Rectifier EPS-01A
The Huawei Rectifier EPS-01A is a 1U or 2U embedded power subrack that provides the mechanical frame, backplane, and distribution terminals for DC power. It is designed to accommodate multiple hot-swappable rectifiers (like the EPW30-48A) and a Monitoring Unit (SMU). It manages the conversion of AC utility power into a stable -48V DC bus, while simultaneously managing battery charging and distribution to various telecommunication boards (BBU, RRU).
