Bel Power Solutions' PES1600 series are 1600 W, Platinum efficient, front-end AC and DC power supplies for powering intermediate bus architectures (IBA) in high-performance and high-reliability servers, routers, and network switches.

The PES1600 power supplies are hot-pluggable and feature parallel operation with active current sharing and full digital controls for improved performance. Cooling is managed by a fan controlled by the DSP controller. PES1600 delivers a power density of 42 W/in³ and meets 80 PLUS® Platinum efficiency in a compact package measuring 80 mm x 40 mm x 195 mm. An active-ORing device on the output ensures no reverse load current and renders the supply ideally suited for operation in redundant power systems. An always-on +12 V_DC 40 W standby output is provided. The PES1600 was designed to include CRPS features such as a black box event recorder, short time overload capability, and fast overcurrent detection.
