Powering AI processors – 48V vertical power delivery changes the game
AI models demand huge current, driving legacy multiphase designs past 50 phases—causing space, thermal, and control limits Vicor addresses
MIL-COTS PFC Front End AC-DC Front-End Module
Product announced for End of Life. PCN 042318
The MIL-COTS PFC Front End from Granite Power can accept a wide 102 – 264VAC input range, frequencies from 47 to 440Hz and deliver up to 1400W of output power. The MIL-COTS PFC Front End is compliant to selected OV transients of MIL-STD-704F. It also complies to selected conducted emissions and susceptibility portions of MIL-STD-461 when used with the specified external filter. The MIL-COTS PFC Front End has a very low-profile and robust brick construction, compliant to many environments in MIL-STD-810, including shock and vibration.
