About This Part
The Delta ESR48/56AC is a robust, high-performance AC-DC rectifier module from Delta's renowned ESR series, specifically engineered for demanding telecommunications and data centre environments. This compact unit, with dimensions approximately 350x190x120mm, is designed for integration into modular power systems, converting incoming AC utility power into a stable -48V DC output. It serves as a critical component in ensuring continuous and reliable power supply for sensitive network equipment. Key technical specifications typically include a wide AC input voltage range, high power conversion efficiency (often exceeding 95%), and a nominal output of -48V DC, with the '56' in its Part Number ESR48/56AC likely indicating a significant current output capacity, potentially around 56 Amps, translating to approximately 2.7 kW of power. These rectifiers are often hot-swappable, allowing for seamless maintenance and expansion without interrupting system operation, and feature advanced digital control for optimal performance and monitoring. The Delta ESR48/56AC rectifier is indispensable for maintaining the operational integrity of critical infrastructure across various sectors. It is primarily deployed in telecom base stations, central offices, remote shelters, and data centre facilities where a highly reliable -48V DC power source is essential. This module supports a wide array of network platforms, including cellular base transceiver stations (BTS), digital subscriber line access multiplexers (DSLAMs), optical line terminals (OLTs), and various IP routing and switching equipment. Telecom operators, internet service providers (ISPs), and large enterprise data centre providers rely on these units to power their core and access networks. The ESR48/56AC solves the critical problem of converting grid AC power into the precise, stable DC power required by most active network components, ensuring uptime, providing redundancy when deployed in parallel, and enabling efficient power management in complex network architectures.
