Output VSWR without harmonic filter is 1.25:1 max. 2 Prime power AC line unbalance not to exceed 3%. Excess imbalance may cause an increase in residual RF noise (AM, FM and PM). Phase noise increase is typically 2.5 dB / % imbalance. 3 AC current harmonic content: less than 20%, primarily fifth and seventh harmonics. Harmonics must be considered when choosing UPS sources. 4 Lower power consumption can be achieved if power saver (included as standard) is employed when operating below rated output power.
