18kW 9U Intelligent DC Power System with Integrated Precision Power Metering

18kW 9U Intelligent DC Power System with Integrated Precision Power Metering

Product Overview of 18kW 9U Intelligent DC Power System

The 9U 19-inch rack-mounted DC power system delivers 18kW rated output power with -48V DC nominal voltage, purpose-built for telecom base stations, central offices, data centers, and mission-critical network infrastructure. Featuring a hot-swappable N+1 redundant architecture, the system accommodates 6*3000W rectifier modules (N+1 redundancy), enabling live module replacement without service interruption—ensuring maximum system availability.

Control and Monitoring of 18kW 9U Intelligent DC Power System

The 18kW 9U Intelligent DC Power System is equipped with a MC2600 controller, which provides full real-time visibility and proactive management of the entire power chain. The controller continuously monitors input voltage, output current, module temperature, battery status, and load conditions, with all data presented clearly on the built-in LCD display for local operation. For remote supervision, the system supports RS485 communication with SNMP interfaces, enabling seamless integration into network management systems (NMS) and allowing operators to receive instant alarms via email or SMS. The advanced battery management function further extends battery life through temperature-compensated charging, automatic equalization, and periodic boost/float charge control, making it an ideal choice for unattended sites requiring high reliability and low maintenance overhead.

Power Distribution and Protection of 18kW 9U Intelligent DC Power System

The system features a well-structured and safety-hardened distribution layout that ensures clean power delivery to both AC and DC loads. An integrated intelligent power meter provides precise energy consumption tracking, while the AC side offers flexible output options for auxiliary equipment. On the DC side, load distribution is intelligently separated into two priority tiers: LLVD for non-critical loads that can be shed during battery discharge, and BLVD for critical loads that must remain powered as long as possible. Dedicated battery breakers ensure safe and independent battery bank isolation. This tiered disconnection strategy, combined with comprehensive over-voltage, under-voltage, over-current, and over-temperature protections, guarantees stable power delivery while protecting both load equipment and battery assets under all operating conditions.
