Output VSWR without filter is 1.25:1 max. 2Prime 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. 3AC current harmonic content: less than 20%, primarily fifth and seventh harmonics. Harmonics must be considered when choosing UPS sources. 4Lower power consumption can be achieved if power saver (included as standard) is employed when operating below rated output power.
