Please note:
This controller sinks current to the negative load return but does not actively source current.
This means that One of the two load terminals must be connected to the positive terminal of the controller, and the second load terminal must be 'free'. Controller appropriate if you have a motor or other load with two individual leads - but not if the negative return for the load is fixed to the negative feed. If you are unsure about what this means in your application, please ask us to clarify.
