About This Part
The Delta ESR-48/56CN(DPR48/50C) is a high-performance, hot-swappable rectifier module integral to robust DC power systems. As a core component within the Delta power conversion product family, this unit is engineered to deliver reliable and stable -48V DC power from an AC input, typically ranging from 85 to 300VAC. Its primary function is to efficiently convert incoming alternating current into direct current suitable for powering sensitive telecommunications and data centre equipment. The Part Number ESR-48/56CN(DPR48/50C) signifies its capability to provide a substantial output current, often around 50A or 56A at -48V, translating to an output power of approximately 2400W to 2688W. This Delta rectifier module incorporates advanced features such as high power factor correction (PFC) and high conversion efficiency, often exceeding 96%, minimizing energy losses and operating costs. Designed for parallel operation, these modules ensure redundancy and scalability within a power system, enhancing overall system reliability and availability. The Delta ESR-48/56CN(DPR48/50C) rectifier modules are deployed in a wide array of mission-critical environments where uninterrupted DC power is paramount. They are typically installed within dedicated DC power plants or power shelves in telecommunication central offices, mobile base stations (including 2G, 3G, 4G, and 5G infrastructure), and enterprise data centres. These modules are essential for powering network equipment such as switches, routers, servers, and transmission systems, ensuring their continuous operation. Mobile network operators, fixed-line providers, and internet service providers heavily rely on such robust power solutions to maintain network uptime and service availability. In data centre environments, the ESR-48/56CN(DPR48/50C) contributes to the overall power infrastructure, supporting critical IT loads. By providing a stable and regulated -48V DC output, these rectifiers solve the problem of fluctuating AC power, protecting sensitive electronic equipment and extending its operational lifespan. They are frequently used in network expansions or as direct replacements for older, less efficient rectifier units, contributing to reduced operational expenditure through improved energy efficiency.
