About This Part
The Part Number ESR-48/56GZ(DPR48/50G) is a high-efficiency Delta rectifier module, an essential component within DC power systems for critical infrastructure. As part of Delta's renowned power solutions portfolio, this unit is engineered to convert incoming AC utility power into stable -48V DC, which is the standard operating voltage for a vast array of telecommunications and data centre equipment. Its design typically features a compact, hot-swappable form factor, facilitating easy integration and maintenance within power shelves or rectifier racks. Key technical specifications for this class of Delta rectifier often include a wide input voltage range (e.g., 85-300VAC), an output capacity in the kilowatt range (e.g., 5000W to 5600W), and industry-leading power conversion efficiency, often exceeding 95%. This ensures minimal energy loss and reduced operational costs, while providing reliable power delivery to sensitive electronic loads. Advanced features may include active power factor correction (PFC) and digital control for enhanced performance and monitoring capabilities. This Delta rectifier module is primarily deployed in mission-critical environments where uninterrupted DC power is paramount. Typical installations include telecommunications central offices, mobile base stations (BTS), remote radio units (RRUs), and data centre power distribution units (PDUs) or battery backup systems. It supports a wide range of network platforms, from legacy PSTN infrastructure to modern 5G deployments and high-density computing racks, by providing the necessary -48V DC power rail. Telecommunications operators, internet service providers, and large enterprise data centre providers rely on such robust power components to ensure the continuous operation of their network equipment, including switches, routers, servers, and optical transmission systems. The ESR-48/56GZ(DPR48/50G) solves the critical problem of converting unreliable AC grid power into clean, regulated DC power, simultaneously charging backup battery banks to maintain service during AC outages. It serves as an ideal replacement for aging or less efficient rectifier units, or as an expansion module to increase the overall power capacity and redundancy of an existing DC power plant. Revo Distribution Limited specializes in providing high-quality used and refurbished telecom and data centre equipment, including the Delta ESR-48/56GZ(DPR48/50G) rectifier module.
