POWERSTAT Variable Transformers of the 10C, 10C-40 and 12C Series may be connected
to suit various requirements as shown in the RATINGS CHART. The individual units in
types 10C-40-2 and 10C-40-3 are not electrically interconnected but are independently
wired following the type 10C-40 connections. Under “KNOB ROTATION”, rotating the
knob in the direction indicated will INCREASE the output voltage. The dial is marked for
clockwise rotation only.
