About This Part
The Delta ESR-48/40AC is a robust, high-efficiency rectifier module, a critical component within Delta's comprehensive power solutions portfolio. This compact, hot-swappable unit is engineered to convert incoming AC utility power into a stable -48V DC output, crucial for powering sensitive telecommunications and data centre equipment. With an output current capability of 40 Amps, the Part Number ESR-48/40AC delivers approximately 1920 watts of reliable DC power. It typically features advanced power factor correction (PFC) and high conversion efficiency, often exceeding 96%, to minimize energy loss and operational costs. Designed for integration into modular power shelves, these rectifiers support intelligent control and monitoring via standard communication interfaces, ensuring seamless operation and proactive maintenance within a larger DC power system. The Delta ESR-48/40AC rectifier module is widely deployed in various mission-critical infrastructure environments, including telecommunication central offices, mobile base stations (BTS), enterprise data centres, and edge computing facilities. It forms the backbone of the DC power infrastructure, providing reliable energy to network platforms such as optical transmission systems, core routers, switches, and radio access network (RAN) equipment. Telecommunication operators, internet service providers (ISPs), and large enterprises rely on such modules to ensure continuous operation and uptime for their critical services. This module effectively solves the challenge of providing stable, clean DC power, supporting battery charging for uninterruptible power supply (UPS) systems, and mitigating power fluctuations, thereby enhancing network resilience and service availability. It is often used to expand existing DC power plants or upgrade older, less efficient rectifier units. Revo Distribution Limited specializes in providing cost-effective infrastructure solutions to B2B clients globally, and the Delta ESR-48/40AC rectifier module is a prime example of our offerings. We supply used and professionally refurbished units of Part Number ESR-48/40AC, enabling telecom operators and data centre providers to expand or upgrade their networks efficiently without incurring the high capital expenditure associated with new equipment.
