Flywheel UPS
VSS DC
SOCOMEC
Backs up the DELPHYS UPS, overcoming the constraints, risks, costs and hazards of batteries. The solution inverter DELPHYS with dynamic storage of energy VSS+ DC was carried out by SOCOMEC UPS.
PRINCIPLE
VSS+ DC uses a very high-speed, rotating flywheel.The rotating assembly is held up by maintenance-free electromagnetic levitation, with no contact with other parts. A maintenance-free internal system vacuum eliminates friction and maximizes energy efficiency. The flywheel-driven generator supplies energy to the UPS during a power failure, thus providing continuous power to the load. When mains power is restored, the flywheel takes less than 5 minutes to return to full speed.
