Alcatel‑Lucent 8DG02607AA POW100 DC‑DC Converter Module

The Alcatel‑Lucent 8DG02607AA is a high‑performance DC‑DC converter module, designated POW100, designed for use in telecom and networking equipment. This power module converts a nominal –48 VDC input into multiple regulated output voltages, providing clean, stable power to line cards, control modules, and other chassis‑based components. It is a critical element for ensuring system reliability in central offices, data centres, and remote shelters.

The POW100 module features a synchronous rectification topology that achieves high efficiency (typically > 90%) across a wide load range, reducing heat dissipation and improving overall system energy efficiency. It includes comprehensive protection features such as overvoltage, overcurrent, overtemperature, and short‑circuit protection. The module is hot‑swappable, allowing replacement without powering down the entire chassis.

Designed to meet stringent telecom standards, the 8DG02607AA offers excellent ripple and noise suppression, ensuring sensitive digital and analog circuits receive clean power. Its compact form factor allows high‑density packaging in 19‑inch racks.
