    2: General Description For example, a fully populated RI-40 frame (4 x 20 kW UPS modules) would operate with a redundancy of one module when connected to a 60 kW load. Under normal circumstances, with all four UPS modules operating, each module would provide 15 kW when the full 60 kW load is applied.
  • Page 19 2: General Description Operating in this mode is slightly more energy efficient than operating in the ON-LINE mode due to the reduced rectifier and inverter losses during normal system operation; and it is sometimes referred to as the ‘ECO’ (economy) mode. However, this mode is recommended only if the connected load equipment can tolerate power interruptions of up to 3~5 ms during the transfer period.
