About This Part
The Part Number ESR-48/56BC, known as the Delta ESR-48/56BC, is a high-efficiency, hot-swappable rectifier module engineered to provide robust and reliable -48V DC power for critical telecommunications and data centre infrastructure. As a key component within Delta's esteemed power solutions portfolio, this module is designed for seamless integration into existing power shelves and systems. Its primary function is to convert incoming AC utility power into a stable, regulated -48V DC output, essential for powering a wide array of network equipment. Key technical specifications include a nominal -48V DC output with a substantial 56A current capacity, ensuring ample power delivery for demanding loads. These Delta rectifiers typically boast industry-leading power conversion efficiencies, often exceeding 96%, which translates into reduced operational costs and lower heat dissipation within facilities. Equipped with advanced features such as active current sharing, comprehensive protection mechanisms against over-voltage, over-current, and over-temperature, and a compact form factor, the ESR-48/56BC ensures high availability and operational longevity for vital network components. The Delta ESR-48/56BC rectifier module finds extensive deployment across a diverse range of mission-critical environments where uninterrupted -48V DC power is paramount. It is commonly installed in telecommunication central offices, mobile base station sites, enterprise data centres, and various network aggregation points. This module serves as the backbone for powering essential network platforms and systems, including core routers, access switches, optical line terminals (OLTs), wireless base transceiver stations (BTS), and critical server racks that rely on a stable DC power input. Leading telecommunication operators, internet service providers, and large-scale data centre providers globally leverage such Delta power solutions to maintain the integrity and uptime of their infrastructure. The ESR-48/56BC effectively solves the challenge of providing highly reliable and scalable power, mitigating the risks associated with AC power fluctuations and outages by supporting robust battery backup systems. It is frequently utilized for expanding the capacity of existing -48V DC power plants or as a direct upgrade path for older, less efficient rectifier units, thereby enhancing overall system performance and energy efficiency.
