SAN JOSE, USA: Super Micro Computer Inc. extended its innovative leadership in high-efficiency power supply technology by unveiling a series of new digital switching power supplies that provide additional 5-10 percent efficiency gains at light loads and the highest levels of efficiency across a wider load range in comparison to today's mainstream analog switching power supplies.
Supermicro's new Platinum-Level (95 percent+) high-efficiency power supplies utilize high-speed digital power controllers with adaptive switching in place of conventional analog circuitry to generate PWM control signals. In analog power supplies, efficiency is optimized for a single load value based on a system's typical operation. As the load shifts away from the peak, efficiency drops.
With this new digital control, compensation and output parameters can be dynamically configured to match different load conditions resulting in increased efficiency across a wider range of operation. Supermicro's Digital switching power supplies also provide faster transient response to input AC line voltage fluctuations resulting in a <5 percent Input Current THD for an increased stability margin.
Supermicro's PWS-1K43F-1R, PWS-1K28P-SQ, PWS-605P-1H and PWS-341P-1H are the first in a series of new Digital switching power supplies, delivering output from 340 to 1400 Watts. These supplies feature Platinum Level (95 percent+) efficiency, Remote Monitoring with PMbus 1.2, node management support, SMBAlert and are Energy Star Server 2.0 ready. These Digital switching power supplies are optimized for select Supermicro 1U to 4U SuperServers and are ideal for Data Center, Enterprise, Cloud Computing, HPC and many other resource intensive computing applications.
