Product Overview of 30kw Rectifier Power System Intelligent DC Power
The ET48750-M7E1010 DC rack power system provides a high-capacity, resilient DC power solution designed specifically for telecommunications infrastructure, data center operations, and industrial applications requiring dependable DC power distribution. 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 30kW, this system reliably supports high-demand installations while achieving power conversion efficiency exceeding 96%.
The DC distribution panel is equipped with 2*250A/2P battery circuit fuse and includes 2*LLVD and a BLVD functionality for secure and flexible power management. System intelligence is provided by a dedicated controller featuring 3 analog sensor inputs, 7 digital status inputs, and 6 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.
