  • Page 8: Operating Modes

    OPERATING MODES Liebert Trinergy™ Cube 2. OPERATING MODES 2.1. Functions Trinergy™ Cube incorporates the three existing standard topologies into one transformer-free UPS: Maximum Power Control mode (IEC 62040-3 VFI): This is the double conversion mode which provides the highest level of power conditioning. It protects the load from all types of electrical network disturbances that would use a greater amount of energy.
  • Page 9 Liebert Trinergy™ Cube OPERATING MODES Dynamic Online - High Efficiency & Power Conditioning mode (IEC 62040-3 VI): This mode compensates for output load THDi, output load PF. It reduces line power disturbances such as sags and swells. The load is fed by the bypass line, and the inverter works as an active filter, which compensates for the reactive power required by the load.
