18kW High Efficiency Rack-mount DC48V Telecom Rectifier System LLVD BLVD
Product Overview of 18kW DC48V Telecom Rectifier System
The 18kW rack-mounted DC power system is a high-capacity solution designed for telecom networks, data centers, and industrial facilities requiring reliable DC supply. It supports 220V single phase input, delivering a stable –43 to –58VDC output with a rated value of –53.5VDC. With a maximum capacity of 18kW, this system ensures sufficient power for large-scale applications while maintaining efficiency above 96%.
The system integrates up to 6 rectifier modules(N+1 redundancy), each rated at 3000W and weighing ≤2kg. These modules feature forced cooling, high power factor ≥0.99, and THD ≤5%, ensuring clean and stable DC power conversion. With front maintenance, top cable entry, and IP20 protection, the design prioritizes safety, serviceability, and ease of integration into 19-inch racks.
DC distribution includes 2*125A battery breakers and 1*LLVD & 1*BLVD, providing flexible and secure load management. The intelligent controller supports 3 analog inputs, 7 digital inputs, 6 dry contact alarms, and remote communication via RS232/485 and SNMP. Local monitoring is enabled through an LCD display.
Built for challenging environments, the unit operates from –40℃ to +65℃, withstands 5–95% non-condensing humidity, and maintains stable operation at altitudes up to 3000m. With its modular architecture and robust performance, the 18kW 5U DC power system is an ideal choice for critical infrastructure requiring scalable and dependable energy solutions.
