  • Integrated soft start and safety shutdown
    Patent number: 10135367
    Abstract: The subject matter of this specification can be embodied in, among other things, a current control assembly that includes an electrical current flow path having a maximum current flow rate, a first current limiter in the electrical current flow path, the first current limiter comprising circuitry configured to adjustably restrict current flow along the electrical current flow path to a flow rate less than the maximum current flow rate in response to receipt of a first signal at a first input port, and a second current limiter in the electrical current flow path, the second current limiter arranged to interrupt the electrical current flow path in response to receipt of a second signal at a second input port.
