High Light 3-27kW rack-mount DC power systemmodular 3000W telecom rectifierhigh-efficiency 7U telecom power system

High-Capacity 3–27kW 7U Rack-Mount DC Power System, Modular 3000W Rectifiers, Wide AC Input, >96% Efficiency

 

Product Overview

 

The 3–27kW 7U 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 both 380VAC three-phase and 220VAC single-phase input, delivering a stable –43 to –58VDC output with a rated value of –53.5VDC. With a maximum capacity of 27kW, this system ensures sufficient power for large-scale applications while maintaining efficiency above 96%.

 

The system integrates up to nine rectifier modules, 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 six 125A battery breakers and four 63A load breakers, providing flexible and secure load management. The intelligent controller supports 4 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 3–27kW 7U DC power system is an ideal choice for critical infrastructure requiring scalable and dependable energy solutions.
