Alcatel-Lucent 8DG07990AAAA02 PSF-320 (NGP1AC0KAA) Power Supply Unit

The Alcatel-Lucent 8DG07990AAAA02 PSF-320 (Power Shelf - 320 Ampere) with designation NGP1AC0KAA is a high-capacity DC power distribution system engineered for reliable −48 V DC power conversion, regulation, and distribution in telecommunications central offices, data centers, and network infrastructure facilities. This module provides critical power conversion and distribution functionality including AC-to-DC conversion, voltage regulation, overcurrent protection, thermal management, battery backup integration, and redundant power system support to ensure continuous operation of telecommunications switching systems, transmission equipment, data networking platforms, and wireless infrastructure. The PSF-320 power shelf implements sophisticated power conversion functionality with 320 Ampere total output capacity, active power factor correction (PFC) meeting IEC 61000-3-2 harmonic current emission limits, high-frequency switching regulation with typical efficiency exceeding 90-93%, wide AC input voltage range tolerance (200-240 VAC or 380-415 VAC three-phase, 50/60 Hz), and comprehensive fault detection for loss of input power, overvoltage, undervoltage, overcurrent, overtemperature, ground fault, and fan failure conditions. The NGP1AC0KAA variant designation indicates specific configuration parameters including input voltage range, output current rating, connector types, and monitoring capabilities optimized for next-generation platform deployments. Advanced features include modular rectifier architecture with hot-swappable rectifier modules enabling field replacement and capacity expansion without service disruption, integrated battery management system with charging control, temperature compensation, and battery testing capabilities, automatic load sharing between parallel rectifier modules, comprehensive alarm and status reporting for proactive maintenance and rapid fault isolation, and remote monitoring capabilities through integrated monitoring unit. The power shelf features robust mechanical construction with reinforced AC input terminals, DC output busbars or distribution panels, integrated cooling fans with redundancy and tachometer monitoring, strain relief for power cables, and secure rack-mounting hardware ensuring reliable installation in standard 19-inch or 23-inch telecommunications equipment racks. Integration with facility DC power distribution systems provides connectivity to battery banks for backup power support, DC distribution panels for load feeders, and grounding systems for safety and electromagnetic compatibility. Management interfaces include RS-485, RS-232, Ethernet, SNMP v3, Modbus, and proprietary monitoring protocols for integration with Alcatel-Lucent's facility management systems, building management systems (BMS), data center infrastructure management (DCIM) platforms, and third-party power monitoring systems, providing access to input voltage and current per phase, output voltage and current, load sharing status, rectifier module status, battery voltage and charging current, temperature readings, fan speed, efficiency metrics, alarm status, event logs, and comprehensive diagnostic information. The PSF-320 supports redundant N+1 or N+N rectifier module configurations with automatic load sharing, current sharing, and graceful degradation upon rectifier module failure, ensuring carrier-grade availability exceeding 99.999%. The power shelf features comprehensive electromagnetic compatibility (EMC) design per EN 300 386, FCC Part 15 Class A, and CISPR 32 standards with integrated filtering to prevent conducted and radiated electromagnetic interference. Safety features include integrated circuit breakers or fuses for overcurrent protection on AC input and DC output, overvoltage protection with crowbar circuits, overtemperature protection with thermal shutdown, ground fault detection, isolation transformers or galvanic isolation for safety separation, surge protection devices (SPD) for lightning and transient protection, and compliance with international safety standards. Power output specifications include regulated −48 V DC (nominal, floating) with tight voltage regulation tolerance typically ±2% (−43.2 to −56.4 V DC operating range per ETSI EN 300 132-2), low output ripple and noise below 200 mV peak-to-peak, and total output current rating of 320 Amperes with individual rectifier modules typically rated at 40A, 50A, or 100A depending on configuration. The power shelf implements intelligent thermal management with variable-speed cooling fans, temperature-based fan speed control, redundant fan architecture, and thermal shutdown protection to maintain optimal operating temperatures. Battery integration features include programmable charging algorithms (constant current/constant voltage CC/CV), temperature-compensated charging per IEC 60896 specifications, battery test and discharge monitoring, low voltage disconnect (LVD) protection, and support for valve-regulated lead-acid (VRLA), flooded lead-acid, or lithium-ion battery technologies. 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 +40 °C (with derating above 40 °C) and relative humidity from 5% to 95% non-condensing. The PSF-320 power shelf is validated for deployment in Alcatel-Lucent telecommunications central offices, wireless base station sites, data centers, and network infrastructure facilities powering 5520 AMS, 5620 SAM, 7750 SR, 7450 ESS, 1650SM/1660SM/1670/1696MS optical transport platforms, and related telecommunications and data networking equipment, and ensures compliance with IEC 60950-1/IEC 62368-1 (safety), IEC 61000-4 (EMC immunity), ETSI EN 300 132-2/300 132-3 (DC power supply interfaces), Telcordia GR-63/GR-1089 (NEBS), IEEE 484/1187 (battery installation), RoHS/WEEE directives, and CE/FCC marking requirements for carrier-grade DC power distribution systems in telecommunications and data center infrastructure.
