Not quite, it's an interesting device. It uses some sort of pulse modulation to limit the current but it always operates at the same voltage. You use a pot to adjust the amount of current sent to the pump at idle and then you send voltage to a terminal to trip it into full current. They say it is a 0.5v drop vs alternator voltage at 20amps.
