The Voltrix S6K (Tower) and RS6K (Rack 2U) are 6 kVA / 5.4 kW high-frequency online double-conversion (VFI) UPS systems with a built-in maintenance-free VRLA battery (12×12V/7AH). 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. A long-backup external-battery variant (S6KL / RS6KL) is available separately.
