Benefit2 Total Efficiency higher than 90% with reducing the number of conversion! High efficiency with real loading factor, unlike UPS Intensive PS system with central power supply unit in server rack Reduction of electricity charge Non-stop maintenance and expansion through n+1 redundancy! Seamless connection to battery during power outage! Less conversion! Eliminating PS form ITE, long-lasting, highly-reliable! Fanless, liquid-capacitor less! Energy-saving effect High reliability Solving high voltage-current problems! Arc suppression circuit Middle point ground Benefit3 Safety The future technology Solar power LED Illumination Fuel cell Cooling system with outside air Superconductors etc Benefit4

PS rack DC340V DC HVDC PDU DC340V HVDC Server rack DC Server() Mother board CPU Memory HDD Key technology : Middle point ground The current is limited within safety current for human through high resistors of 47KΩ. Central Redundant Power Supply Key technology : Bus bar Dangerousness by the high voltage had been pointed out. But,,, Key technology : Arc suppression circuit W/O Suppression Circuit W/ Suppression Circuit Resolved the arc discharge issue at the time of switch-on/off and disconnection.
