About This Part
The Delta ESR-48/40AC(DPR48/30-D-DCE) is a robust, hot-swappable rectifier module designed for high-availability DC power systems. As part of Delta's renowned ESR-48/40AC product family, this specific module, identified by Part Number ESR-48/40AC(DPR48/30-D-DCE), serves as a critical component in converting incoming AC utility power into stable -48V DC output. Each DPR48/30-D-DCE module typically delivers up to 30 Amperes of current, contributing to a total system capacity that can reach 40 Amperes or more, depending on the system configuration. Engineered for demanding B2B environments, it features high power conversion efficiency, often exceeding 95%, which minimizes energy loss and operational costs. Its compact form factor allows for integration into standard telecom racks, ensuring optimal space utilization while providing reliable and regulated power essential for sensitive electronic equipment. Key technical specifications include a wide AC input voltage range, active power factor correction, and advanced monitoring capabilities for system health and performance. This Delta rectifier module is indispensable in a variety of mission-critical applications across the telecommunications and data centre sectors. It is commonly installed in DC power plants within cellular base stations, central offices, enterprise network facilities, and colocation data centres, providing the necessary -48V DC power to operate network switches, routers, servers, optical transmission equipment, and radio access network (RAN) components. Telecom operators, internet service providers (ISPs), and large enterprise IT departments rely on such modules to ensure continuous operation and power redundancy for their core infrastructure. The ESR-48/40AC(DPR48/30-D-DCE) solves the fundamental problem of converting grid AC power into the precise DC voltage required by most telecom and networking hardware, thereby preventing service interruptions due to power fluctuations or outages when paired with battery backup systems. It frequently serves as an upgrade or replacement for older, less efficient rectifier units, enhancing overall system reliability and energy efficiency.
