SG2K-2TXI Output Configuration
The SG2TXI model provides three galvanically isolated 240Vac and 120Vac outputs. The
two 120Vac receptacles are derived split phase from the isolated, center tapped 240Vac
output. The center tap has been grounded to provide a derived neutral for both 120Vac
outlets. Due to this, the 120V load is divided between the two 120Vac receptacles. The
combined load on all outputs must never exceed 1400 wats.
SG3K-2TX Output Configuration
The SG3K-2TX model provides galvanic isolation only on the 120Vac outlets. The 120Vac
outlets have been limited to a 1400 watt maximum output. The 208-240Vac output is
derived directly from the UPS inverter, which is not isolated. The combined load on all
outputs must never exceed 2100 watts.
