APPLICATIONS
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.

• Environmentally-friendly
THE VARIOUS CONFIGURATIONS Various solutions or combinations for meeting your requirements for electrical energy availability are possible depending on your operating constraints and technical environment.
1. short-duration POWER OUTAGES The VSS+ DC system is connected to the DC bus; it supplies the inverter when the low-voltage system exceeds the voltage tolerances. Thereby providing 99.5% protection against system failures.
2. working with a generator unit The VSS + DC supplies the inverter long enough for an emergency generator to take over the power supply and rapidly recharge the VSS + DC.
3. working with a battery When connected in parallel with a battery bank, the VSS+ DC cuts in during all short power failures and voltage sags; battery backup is used only for long duration cuts (or not at all if a backup generator is present). Battery life is extended by very infrequent demands.
4. working in parallel VSS+ DC units connected in parallel increase power and available backup time. No communications hardware or software needed, this capability is built-in.
