Description

DC48V 3U BTS Telecom Rectifier Systems with RS485 Remote Monitoring

Product Overview of 3U BTS Telecom Rectifier System

The ET48300-M5E63 is a DC rack power system developed by ESTEL, 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 (compatible for single-phase and three-phase) 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 18kW, this system reliably supports high-demand installations while achieving power conversion efficiency exceeding 96%.

The DC distribution panel is equipped with 1*250A battery circuit breakers and includes LLVD & 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.
