About This Part
The Delta ESR-48/56CZ(DPR48/50C) is a robust and high-performance rectifier module designed for critical DC power applications within telecommunications and data center environments. As a core component of a larger power system, this module efficiently converts incoming AC utility power into a stable -48V DC output, essential for powering network equipment such as routers, switches, servers, and transmission systems. Part of Delta's renowned ESR series, it typically features a compact, hot-swappable form factor, allowing for easy integration into standard power racks and facilitating seamless maintenance or expansion without system downtime. Key technical specifications often include high power conversion efficiency, frequently exceeding 95%, active power factor correction (PFC) for reduced energy consumption, and a wide input voltage range to ensure reliable operation under varying grid conditions. Its design supports parallel operation, enabling N+1 redundancy configurations and scalable power capacity to meet evolving infrastructure demands. This Delta rectifier module is extensively deployed across various critical infrastructure sectors. It is a foundational element in telecom central offices, mobile base stations, enterprise data centers, and internet service provider (ISP) facilities, where uninterrupted and stable DC power is paramount. The ESR-48/56CZ(DPR48/50C) addresses the critical need for reliable power delivery, mitigating risks associated with power fluctuations or outages and ensuring continuous operation of vital communication and data processing equipment.
