The new Protect C UPS from 1000 to 3000 VA power represent consistent further development of the well-proven and highly reliable series. With the lag increased to 0.9, the power factor was taken into account for the demand for higher performance active consumers. The ECO and frequency inverter for operation mode highlights the requirements for a modern versatile UPS. 6 & 10 kVA: Highly integrated switches and a robust IGBT module reduce the number of electrical connections and components and therefore provide for increased reliability. A Static Bypass Switch (SBS) and/or an automated bypass ensure additional safety in case of overload.
