ESS - Energy Saver System
With 99% leading market efficiency, your UPS can pay for itself by dramatically reducing facility power and cooling costs.
ESS allows a dramatic increase in UPS operating efficiency without scarifying load protection. Market leading 99 percent efficiency reduces the overall infrastructure energy consumption resulting in significant operating cost savings thus putting the money back into the budget.
In ESS mode the UPS safely provides mains current directly to load when the input is within the acceptable limits by its voltage and frequency. Superior detection and control algorithms allow the UPS to engage power converters in less than two milliseconds time when utility source goes out of pre-defined limits by its voltage or frequency, thus always providing secured power to the critical load while maximising efficiency.
ESS is currently available on the Power Xpert 9395 and Eaton 9390 UPS products.
