Refer to Table D for AC input specifications.
AC line current shown is for NRU with basic capacity control transformer. Refer to Table E for AC input current if you have selected a control
power source upgrade option.
Refer to Table D for NRU overload capability.
Rated DC bus kW is the power available on the DC thru bus. This value is independent of control transformer selection. To calculate the input
kVA, use this formula:
V = Input Voltage, line to line (V AC, i.e. from column 1)
A = Input Current (A AC, i.e. from column 2)
