Curtis PMC 1204/1205 Manual
load. You should determine by experiment the proper resistor value to
give the desired speed reduction. (NOTE: with reduced speed operation,
only top speed is reduced; full power is maintained for starting at low
speeds.)
Unlike resistor controllers, Curtis PMC 1204/1205 controllers op-
erate efficiently in the reduced speed mode, because little power is lost
through the controller.
Electronic Throttle Wiring
Curtis PMC’s electronic throttle, ET-XXX, is wired as shown in Figure 14.
It requires a controller with the optional 0–5V throttle input.
