POWERSTAT® Variable Transformers of the Q116U, Q117U, Q216U and Q217U Series are available in manually operated assemblies for single and three phase service. The Q116U and Q117U Series operate from 120 volt lines and the Q216U and Q217U Series operate from 240 volt lines.
All models have POWERKOTE coils. The rated output for constant current loads is 9 amperes for the Q116U Series; 10 amperes for the Q117U Series; 3.5 amperes for the Q216U Series; and 5 amperes for the Q217U Series.
For constant impedance loads, the maximum rated output current at line voltage is increased to 12 amperes for the Q116U Series; 13 amperes for the Q117U Series; 5 amperes for the Q216U Series; and 7 amperes for the Q217U Series. The units are of open construction and have no screening, fuses, line switches, terminal enclosures, input cords or output receptacles. They have removable shafts which can be extended from either end of the assemblies.
