Alcatel-Lucent 3AL94247AA AA04 PSUP1000 Power Supply Unit

The Alcatel-Lucent 3AL94247AA AA04 PSUP1000 is a high-capacity power supply unit engineered for reliable DC power distribution, conversion, and management in optical transport network platforms and telecommunications equipment racks. This module provides regulated −48 V DC power distribution with 1000W output capacity to installed line cards, service interface boards, cross-connect modules, control units, transceiver boards, and other shelf-resident equipment in transport platform enclosures including the 1650SM, 1660SM, 1670, 1696MS, and related Alcatel-Lucent optical transport systems. The PSUP1000 (Power Supply Unit 1000W) implements redundant power feed architecture with integrated filtering, voltage regulation, and protection circuitry to ensure clean, stable power delivery with minimal voltage ripple (typically <50mV peak-to-peak) and electromagnetic interference (EMI). The module features automatic load sharing between redundant power feeds, overcurrent protection with resettable circuit breakers or electronic current limiting, overvoltage protection with crowbar circuits, undervoltage lockout (UVLO), reverse polarity protection, inrush current limiting, and hot-swappable design enabling field replacement without service disruption. Advanced features include input voltage monitoring (typically −36 V DC to −72 V DC operating range), output current measurement with ±3% accuracy, output voltage regulation within ±2%, temperature sensing at multiple points, power good status indication, remote on/off control, power sequencing management, and comprehensive alarm reporting for undervoltage, overvoltage, overcurrent, overtemperature, fan failure, and power feed failure conditions. The power supply unit implements high-efficiency switching regulator topology (typically >85% efficiency at full load) with power factor correction (PFC) per EN 61000-3-2 specifications to minimize harmonic distortion and optimize energy consumption. Integration with the transport shelf backplane provides high-current power distribution paths through dedicated power planes and communication with the system control processor through I²C, SMBus, or PMBus interfaces for remote monitoring and management. Management interfaces include SNMP v3, TL1, IPMI-compatible protocols, and proprietary element management system protocols for integration with Alcatel-Lucent's 1350 OMS, NuWave EMS, and third-party network management systems, providing access to input voltage levels, output voltage and current readings, temperature sensors, power consumption statistics, efficiency metrics, operating hours, and alarm/warning conditions with configurable thresholds. The module features robust electromagnetic compatibility (EMC) filtering per EN 300 386, FCC Part 15 Class A, and CISPR 22/32 standards to prevent conducted and radiated interference with other equipment. The PSUP1000 incorporates N+1 or 2N redundancy configurations with automatic failover, load sharing algorithms ensuring balanced current distribution across parallel units, and graceful degradation during fault conditions. Cooling is provided by integrated temperature-controlled fans or convection cooling depending on configuration, with fan speed control based on thermal load to optimize acoustic noise and power consumption. Environmental specifications comply with ETSI EN 300 019 Class 3.1 and NEBS GR-63 Level 3 standards, supporting continuous operation in controlled telecommunications facilities with ambient temperatures from 0 °C to +45 °C (with derating above +40 °C) and relative humidity from 5% to 95% non-condensing. The PSUP1000 is validated for deployment in Alcatel-Lucent 1650SM/1660SM/1670/1696MS/1830/1850 series transport platforms and ensures compliance with Telcordia GR-487, ETSI EN 300 132, NEBS GR-487, IEC 60950-1/62368-1, UL 60950-1, and CSA C22.2 No. 60950-1 standards for telecommunications power systems, safety, and distribution equipment.
