ABSTRACT:
An apparatus that is usable with a well includes an power converter and a controller. The power converter translates electrical power into hydraulic power downhole in the well to generate a first hydraulic signal to cause a downhole tool to transition to a first state and a second hydraulic signal to cause the tool to transition to a different second state. The controller responds to stimuli that are communicated from the surface of the well to cause the actuator to generate one of the first and second hydraulic signals.
