Product Description

DC48V 24kw One Stop Rectifier System Intelligent Telecom Power Rack Mount

Product Overview of DC48V 24kw One Stop Rectifier System

The ET48400 is DC rack power system a 19-inch sub-rack power system produced by ESTEL, with 5U height compactdesign for critical applications of fiber and microwave transmission,access devices, switches, etc. Thesystem maximum power is 400A, with circuit breakers for AC input, batteries and loads.The cables arefront accessing with circuit breakers and busbar. It accepts 380VAC three-phase input and delivers a stable DC output adjustable between –43VDC to –58VDC, with a nominal operating point of –53.5VDC. Offering a maximum output capacity of 24kW, this system reliably supports high-demand installations while achieving power conversion efficiency exceeding 96%.

The DC distribution panel is equipped with 4*100A/1P battery circuit breakers and includes 2*scalable LLVD and a BLVD(Battery Low Voltage Disconnect) functionality for secure and flexible power management. System intelligence is provided by a dedicated controller featuring 3 analog sensor inputs, 8 digital status inputs, and 8 configurable dry-contact alarm relays. Remote monitoring and management are enabled via RS232/485 and SNMP interfaces, while an integrated LCD display allows for local status viewing and configuration.
