2: General Description Advanced input booster/rectifier technology The PowerWAVE 8000DPA RI (S2) UPS module’s advanced booster technology results in an input power factor of 0.99 with a harmonic content of < 3% THD(i). This enhances the system reliability and minimises the winding losses of any generator or transformer connected to the UPS input, which in turn reduces the generator/transformer costs.
2: General Description Note: A brief load break will occur when transferring from bypass to inverter following a bypass supply failure, or if the bypass/inverter are not synchronised when a transfer is demanded. (See ‘Off Line Mode’ in section 2.3.4). Automatic battery changeover switch If the UPS mains input supply fails, or undergoes a sustained dip (brownout), the automatic battery switch will close to connect the battery to the DC boost converter input.

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.
