6U Telecom DC48V Integrated Rectifier Power System with Remote Control
6U Telecom DC48V Integrated Rectifier Power System with Remote Control
Product Overview of 6U Telecom DC48V Integrated Rectifier Power System
Engineered for demanding telecommunications, data center, and industrial applications, the ET48400-M5E86B DC Rack Power System delivers resilient, high-capacity DC power. It accepts a 380VAC three-phase input, providing a stable, adjustable output from –43VDC to –58VDC (typically –53.5VDC) at a maximum capacity of 24kW and efficiency exceeding 96%.
The modular design supports N+1 redundancy with up to eight 3000W rectifier modules, each offering high-efficiency conversion with a power factor ≥0.99 and THDi ≤5%. Housed in a service-optimized 6U chassis with front access and top-panel cabling, the system simplifies installation and maintenance. Its DC distribution panel includes 4*100A/1P battery circuit breakers, scalable LLVD, and BLVD for flexible power management.
A dedicated controller with analog/digital inputs and configurable alarm relays, alongside RS232/485 and SNMP interfaces, provides comprehensive local and remote monitoring. Designed to operate reliably in extreme environments (–40℃ to +65℃, up to 95% RH, 3000m altitude), this system offers a robust and scalable power foundation for critical infrastructure.
