About This Part
The Delta ESR-48/56AC is a highly efficient, hot-swappable rectifier module integral to robust DC power systems. As part of Delta's renowned power solutions portfolio, this unit is engineered to convert incoming alternating current (AC) power from the utility grid into a stable, regulated direct current (DC) output, typically at 48V. Its primary function is to provide reliable power to sensitive telecommunications and data centre equipment, ensuring continuous operation. Key technical specifications for such a module often include a wide AC input voltage range (e.g., 85-300VAC), a nominal 48V DC output, and a substantial output current capacity, indicated by the '56AC' in its designation, suggesting up to 56 Amperes. These modules are characterized by high power density, superior energy efficiency (often exceeding 96%), and advanced protection features against overvoltage, overcurrent, and overtemperature, making them critical components in maintaining system uptime. This Delta rectifier module finds widespread application in diverse network environments requiring dependable DC power. It is commonly installed in power shelves and racks within telecom base stations, central offices, data centres, and enterprise network facilities. Mobile network operators, fixed-line providers, internet service providers, and cloud service providers are primary users, relying on such modules to power their critical active equipment, including switches, routers, servers, and radio access network (RAN) components. The ESR-48/56AC solves the fundamental problem of converting unstable AC grid power into the precise DC power required by network infrastructure, while also supporting battery charging for backup power. It serves as an essential component for expanding existing power capacity or upgrading older, less efficient power conversion systems. Revo Distribution Limited specializes in providing cost-effective infrastructure solutions to B2B clients, and we frequently offer used and refurbished units of the Part Number ESR-48/56AC. By supplying high-quality, pre-owned Delta rectifier modules, Revo enables telecom operators and data centre providers to expand or upgrade their networks efficiently without incurring the substantial costs associated with new equipment procurement. Our inventory of refurbished power components, including the Delta ESR-48/56AC, extends the operational lifecycle of existing infrastructure, providing a sustainable and economically viable alternative for maintaining and enhancing critical network uptime. Revo is committed to delivering reliable equipment that meets the stringent demands of modern telecommunications and data centre operations.
