30kw 9U Rack Mounted Intelleigent Telecom Rectifier Power Distribution System with LLVD BLVD
Product Overview of 30kw 9U 19'' Rack Mounted Telecom Rectifier System
The 30 kW DC48V rectifier system is a high-capacity power solution engineered to guarantee uninterrupted DC power for telecommunications, data centers, and critical industrial processes. Operating from a 380VAC three-phase input, it produces a precisely regulated DC output adjustable from –43 VDC to –58 VDC, with a nominal setpoint of –53.5 VDC. With industry-leading conversion efficiency exceeding 96% even at full load, it is exceptionally well-suited for energy-optimized, high-density deployments.
The integrated distribution panel includes both LLVD (Limited Load Voltage Disconnect) and BLVD (Battery Low Voltage Disconnect) functions for intelligent, flexible load management. The system is managed by a sophisticated onboard controller offering extensive monitoring and configuration options. It features 3 inputs for ambient temperature sensors, 7 digital inputs for external status monitoring, and 6 programmable dry-contact relay outputs for comprehensive alarm management. Remote oversight is supported via RS485 and SNMP interfaces, while an intuitive front-panel LCD screen enables convenient local configuration and real-time status checks.
