PES2200 Series Front-End Power Supply

Bel Power Solutions' PES2200 Series, 2200 W high-density power supplies feature full digital control for servers, storage and networking equipment, and other high-availability applications. With totem-pole bridgeless power-factor-corrected (PFC) and soft-switching resonant techniques in conjunction with synchronous rectification DC-DC stage, the AC-input model can achieve beyond Platinum efficiency.

The DC-input model uses an interleaved forward converter topology with active clamp and synchronous rectification to reduce component stresses, thus providing increased system reliability and very high efficiency. An active OR-ing device on the output ensures no reverse load current and renders the supply ideally suited for operation in redundant power systems. PES2200 Series power supplies provide a main output of 12 V_DC for powering intermediate bus architectures (IBA) in data center and telecom central office equipment.

The convergence of IT and telecom infrastructures means that computing servers, storage appliances, routers, and networking switches may be installed in data centers with AC input power or -48 V_DC telecom environments. Manufacturers of computing, network and storage equipment can use the PES2200 Series to simplify the integration and servicing of their servers and appliances.

The PES2200 Series provides a high-efficiency and feature-rich power source for servers running web and email applications, databases, streaming games or movies, or providing storage, as well as routers, and network switches. This high-performance computing equipment is being used in applications and services such as multi-access edge (MEC) computing, enterprise edge computing, real-time communications, cloud services, and virtualized applications.
