The HHY48400-H8A5KM is a state-of-the-art, 19-inch rack-mounted embedded DC power supply system specifically engineered for modern telecommunications and base station applications. Delivering a robust 24kW maximum capacity and up to 450A of rated output current, it ensures a highly stable 53.5VDC power source for critical network infrastructure under diverse grid conditions.   This modular sub-rack accommodates up to six HHY4875G1 4000W hot-swappable rectifiers, achieving an exceptional peak efficiency of 96.2% to significantly reduce operational energy costs. It features a highly reliable power distribution framework, including dual AC inputs (compatible with 380V 3-phase and 220V single-phase), separate LLVD and BLVD load management, and integrated Level C Surge Protection Devices (SPD) on both AC and DC lines for ultimate equipment safety.

An independent embedded DC power system 48VDC 200A-400A 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 27kW (400A). 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 9 (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.
