Alcatel Lucent Rack Charger for 2x 1kW Power Supply

Deliver up to 2000W of reliable -48V DC power from a single 1U rack space with the Alcatel-Lucent 3EH76190AA rack charger shelf. Engineered for telecommunications and data center environments, this shelf accommodates two hot-swappable 1kW power supply units, enabling N+1 or 1+1 redundancy without service interruption. The integrated management interface supports SNMP and web-based monitoring, while forced-air cooling and comprehensive protection circuitry ensure continuous operation in demanding conditions.

Overview

The Alcatel-Lucent 3EH76190AA is a 19-inch rack-mountable DC power rectifier shelf designed to house two 1000W power supply modules. It converts 100-240V AC input to -48V DC output, providing a total capacity of 2000W when both slots are populated. The shelf occupies only 1U of rack space and features hot-swappable PSU bays, allowing power modules to be replaced without powering down the system. Built-in management via Ethernet (SNMP, Web GUI) and RS-232 enables remote monitoring and control of power status, alarms, and battery charging functions.

What stands out

• Dual 1kW PSU slots deliver up to 2000W total output in a compact 1U form factor
• Hot-swappable power supply support for N+1 or 1+1 redundancy configurations
• Integrated SNMP and web-based management for real-time power monitoring and alarms
• Comprehensive protection against overload, overvoltage, short circuit, and overtemperature
• Forced-air cooling maintains optimal thermal performance in 0°C to 50°C environments
