CONTACTOR CONTROL UNITS

A contactor control unit (CCU) includes a communication interface configured to be coupled to a power controller. The CCU also includes one or more switches, each associated with a contactor in a power distribution system that includes one or more contactors and configured to control a driving current for switching the associated contactor between its “on” and “off” power states. The CCU further includes a controller configured to receive, from the power controller, a first signal to switch a power state of a first contactor of the one or more contactors. The controller is also configured to convert the first signal to a control signal applied to the switch associated with the first contactor, receive a second signal indicating a power state of an element controlled by the first contactor, and send the second signal to the power controller.
