An independent embedded DC power system 48VDC 300A-600A can be flexibly provided for any indoor site or outdoor telecom power cabinet if required. Acting as a reliable base station power system, its maximum capacity ranges from 18kW (200A) to 36kW (600A). Based on a new generation rectifier power supply module, it delivers exceptional high efficiency and power density to save electricity and footprint for customers.   Due to its standard 19-inch embedded power structure, this system can be installed seamlessly into various setups. Basic components of the sub-rack include a versatile distribution unit, a smart control unit (SMU), and hot-swappable slots for 6 (200A) to 12 (400A) rectifiers. Low voltage disconnect (LVD) is included for discharge time improvement and optimal battery health. Furthermore, the distribution section of the plant is strategically split into two branches of circuit breaker positions, where the current in each branch is precisely monitored by the controller.
