Alcatel-Lucent 3HE04415AAAC01 DC Power Supply

The Alcatel-Lucent 3HE04415AAAC01 DC Power Supply is a high-efficiency power conversion unit engineered for reliable −48 V DC power generation, regulation, and distribution in Nokia (formerly Alcatel-Lucent) telecommunications equipment platforms including 7750 Service Router, 7450 Ethernet Service Switch, 7250 Interconnect Router, and related carrier-grade networking infrastructure. This module provides critical power conversion functionality including AC-to-DC or DC-to-DC conversion, voltage regulation, overcurrent protection, thermal management, and redundant power system support to ensure continuous operation of telecommunications equipment in service provider core, aggregation, edge network, and data center deployments. The DC Power Supply implements sophisticated power conversion functionality including active power factor correction (PFC) meeting IEC 61000-3-2 harmonic current emission limits, high-frequency switching regulation with typical efficiency exceeding 90-94%, wide input voltage range tolerance for AC variants (100-240 VAC, 50/60 Hz) or DC variants (−36 to −72 V DC per telecommunications standards), and comprehensive fault detection for loss of input power, overvoltage, undervoltage, overcurrent, overtemperature, and fan failure conditions. Advanced features include hot-swappable design enabling field replacement without service disruption to the networking platform, integrated status LEDs for local visual indication of power supply status and fault conditions, remote monitoring capabilities through backplane connectivity to system management processors, and comprehensive alarm reporting for proactive maintenance and rapid fault isolation. The module implements robust mechanical construction with reinforced power connectors, integrated cooling fans with tachometer monitoring, strain relief for power cables, and secure mounting hardware ensuring reliable installation in equipment chassis power bays. Integration with the equipment chassis backplane provides connectivity to system control processors for centralized power management, environmental monitoring, load sharing coordination with redundant power supplies, and integration with the platform's operations, administration, and maintenance (OAM) framework. Management interfaces include SNMP v3, NETCONF/YANG, PMBus, and proprietary element management system protocols for integration with Nokia's Network Services Platform (NSP), 5620 Service Aware Manager (SAM), and third-party network management systems, providing access to input voltage levels, output voltage and current, power consumption, temperature readings, fan speed, efficiency metrics, alarm status, and diagnostic information. The DC Power Supply supports redundant N+N or N+1 power configurations with automatic load sharing, current sharing, and graceful degradation upon power supply failure, ensuring carrier-grade availability exceeding 99.999%. The module 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 overcurrent protection, overvoltage protection, overtemperature protection, ground fault detection, isolation transformers for galvanic isolation, and compliance with international safety standards IEC 60950-1 and IEC 62368-1. Power output specifications include regulated −48 V DC (or +12 V DC, +5 V DC variants depending on platform requirements) with tight voltage regulation tolerance typically ±2%, low output ripple and noise below 200 mV peak-to-peak, and output current ratings ranging from 10A to 50A depending on specific variant and platform requirements. The module implements intelligent thermal management with variable-speed cooling fans, temperature-based fan speed control, and thermal shutdown protection to maintain optimal operating temperatures. 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 DC Power Supply is validated for deployment in Nokia 7750 SR-12/7/3, 7450 ESS, 7250 IXR, 1830 PSS, and related service router, switching, and optical transport platforms, and ensures compliance with IEC 60950-1/IEC 62368-1 (safety), IEC 61000-4 (EMC immunity), ETSI EN 300 132 (power supply interfaces), Telcordia GR-63/GR-1089 (NEBS), RoHS/WEEE directives, and CE/FCC marking requirements for carrier-grade power supply units in telecommunications and data center infrastructure.
