...as shown in the attached circuit diagram. The existing motor is 2.85 ohms, and draws under 5 amps at 14 vdc. This actuator motor is being replaced with a much larger motor that draws up to 15 amps (1.35 ohms) for racing purposes, but the factory controller can only handle 5 amps before it cuts out. So I need an additional controller that takes the pair of factory positioning signals (0-14vdc each) at under 5 amps, and generates an identical set of positioning voltages to the larger actuator at up to 15 amps. A separate fused 14vdc power feed at up to 20 amps is available for the new controller to utilize. The actuator motor does not require speed modulation, but I do need as close to instant response as possible from this new intermediate controller. Circuit board d...
