  1. Need a bi-directional dummy load, electronic or passive for control boxes controlling DC actuator motors to test output voltage and current when an actuator motor is not available. Preferably under different current conditions, that is, the dummy load, would create a load to force the port on the control box to increase or decrease the current output so as to simulate a real load and, preferably, powered by the output port of the control box under test. Looking for a dummy load to cover 10Vdc to 50Vdc with currents up to 7 Amps. Just as in the real situation, the direction on the dc motor, and therefore, the extension of retraction of the shaft, is controlled by polarity reversal from the hand-piece while the wire position remains the same. Some control boxes use direct dc, others use pulsating dc current control. One of the problems with electronic dummy loads is simulating polarity or voltage reversal without changing the power wires around. Any ideas or projects already built of this type you have come across.
