  • Page 6 KEOR COMPACT General UPS description The UPS systems described in this manual are on-line, double conversion; the inverter included in the UPS always supplies energy to the load, whether the mains is available or not (according to the battery autonomy time).
  • Page 7 KEOR COMPACT • Inverter [4] It converts the direct voltage coming from the rectifier or from the DC battery into alternating AC voltage stabilized in amplitude and frequency. The fully digital control of the output sinewave allows to achieve high performances, among which a very low voltage distortion even in presence of high-distorting loads.
  • Page 8 KEOR COMPACT • Bypass operation The load can be switched to bypass either automatically or manually. The manual changeover can be performed by display forcing the load to bypass. In case of failure of the bypass line, the load is switched back to inverter without interruption.
