Three Phase 380V Input 48VDC Output 5U 18kW 96% High-Efficiency Telecom Rectifier

Overview of 5U 18kW 96% Efficiency Telecom Rectifier

In high-capacity telecom environments, power density and operational efficiency directly impact the bottom line. The 5U 18kW rectifier system tackles both with a compact footprint that delivers substantial output while maintaining 96% conversion efficiency—translating to measurable savings on electricity bills and reduced HVAC load year after year. 6*3000W hot-swappable modules in N+1 configuration mean you can pull a module for service without dropping a single volt to your load, keeping critical communications online through maintenance cycles. This architecture not only ensures continuous availability but also simplifies capacity planning—should your power requirements grow, additional modules can be added seamlessly without disrupting existing operations.

Controller of 5U 18kW 96% Efficiency Telecom Rectifier

The MC2600 controller is more than a monitoring interface—it's a command center. With 2 analog inputs (battery temperature and ambient temperature), 8 digital inputs for door contacts, smoke detectors, or other sensors, and 8 dry-contact alarm relays, the system gives you full visibility into site conditions and the flexibility to act on them. Remote management is covered by LAN and RS485 connectivity, with multi-protocol support including SNMP, ModBus, and Ethernet. This means your NOC team can pull real-time data, set thresholds, and receive alerts through the same platform they already use—no additional software or gateways required. The intelligent battery management further extends battery life through temperature-compensated charging, automatic equalization, and adaptive charge-stage transitions, ensuring your backup assets remain healthy and ready when needed.

Power Distribution of 5U 18kW 96% Efficiency Telecom Rectifier

This system is equipped to handle complex load environments without requiring external distribution panels. The DC side offers eight LLVD circuits—ranging from 10A to 63A—for auxiliary and non-priority equipment, allowing automatic load shedding to extend battery runtime during outages. For critical transmission and routing gear, seven BLVD circuits (spanning 16A to 63A) keep essential services running as long as battery capacity permits. This two-tier load prioritization strategy is essential for maximizing uptime of revenue-generating equipment during extended power interruptions. Four 125A/1P battery breakers provide independent isolation for multiple battery strings, enabling flexible capacity planning and safe maintenance procedures. All distribution circuits are fully configurable at the factory or in the field, giving you the flexibility to adapt the system as site requirements evolve over time.

Design of 5U 18kW 96% Efficiency Telecom Rectifier

The system's 380VAC three-phase input supports efficient power conversion with balanced phase loading, reducing input current per phase and simplifying upstream breaker sizing. The 96% efficiency means less waste heat is generated within the cabinet, allowing the system to operate reliably in warmer ambient conditions and reducing the burden on site cooling systems. This is particularly valuable in outdoor cabinets or unconditioned shelters where thermal management is a constant challenge. Built-in protections against over-voltage, under-voltage, over-current, and over-temperature conditions safeguard both the rectifier modules and downstream loads, while the modular design ensures fast mean time to repair through simple module swap procedures.
