Alcatel Tyco Yukon ES760A Rectifier

The Alcatel Tyco Yukon ES760A is a high‑performance rectifier module designed for telecom power systems. This unit converts AC mains input into regulated -48 VDC output, providing power to telecom equipment and simultaneously charging backup batteries. It is part of the Yukon series, known for high efficiency, reliability, and advanced monitoring capabilities. The ES760A is suitable for central offices, data centers, and remote telecom shelters.

Overview

The ES760A rectifier is a modular, hot‑swappable unit that fits into a standard 19‑inch rectifier shelf. It uses high‑frequency switching technology to achieve efficiency up to 94%, reducing energy costs and heat dissipation. The module features active power factor correction (PFC), wide input voltage range, and built‑in controller for parallel operation with other rectifiers. It also supports remote monitoring via RS‑485 or CAN bus, allowing integration with power system controllers.
