Bel Power Solutions Announces PES2200 Series Beyond Platinum Efficiency 2200 W High Density Front-End Power Supply with Full Digital Control

Variants for AC- and DC-input enables server, storage and telecom OEMs to standardize
power entry module across product range, simplifying integration and servicing

Santa Clara, CA [September 26, 2019] Bel Power Solutions, a Bel group company (NASDAQ: BELFA and BELFB) and premier global manufacturer of power management devices, today announced the PES2200 Series, 2200 W high density power supplies with 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 VDC 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 Vdc 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.

Measuring just 80 x 40 x 195 mm (3.15 x 1.57 x 7.68 inches), the PES2200 Series has a power density of 59 W/in3 and provides a 12 V output plus an always-on 12 V standby output at 3.5 A. Digital control, programming and monitoring using the Power Management Bus protocol improves the ability of OEMs to control the power supply while increasing reliability and efficiency over a wide operating range.

The PES2200 Series is available from DigiKey, Mouser and Arrow. For more detailed information on the PES2200 Series, visit here (AC-DC/HVDC) and here (DC-DC).
