The Voltrix S10KL (Tower) and RS10KL (Rack 2U) are 10 kVA / 9 kW high-frequency online double-conversion (VFI) UPS systems with a long-backup external battery bank (192V/240V). With 0 ms transfer time, input power factor correction of 0.99 at full load and a wide 110~300V (half load) 176~300V (full load) input window, they protect servers, network equipment and control systems against outages, sags, surges and frequency variation.
Both form factors share identical electrical performance; choose Tower for desktop or floor placement, or the 2U Rack model for standard 19-inch cabinets. The external battery module is ordered separately and sized to the autonomy required — runtime is therefore set by the battery bank, not by the UPS. A standard built-in-battery model (S10K / RS10K) is available separately.
