Patent ID: 7800875

Claim:
A multi-level over-current electronic protection system for protecting a plurality of outputs, comprising: a first solid state reversibly interruptible electronic switch including first output control logic and a plurality of first controlled output channels controlled by said first control logic, said first switching device being coupled to receive power from at least one power supply selected to power a plurality of loads, said first electronic switch providing said power at its plurality of first output channels under normal operating conditions, wherein said first output control logic is operable for reversibly interrupting said power at any of said first output channels when said current in any of said first output channels exceed limits for said first output channels; at least one second solid state reversibly interruptible electronic switch including second control logic and a plurality of second controlled outputs control by said second control logic, a power supply input of said second electronic switch coupled to one of said plurality of first controlled output channels to receive said power, wherein said second controlled outputs are coupled to provide said power to said plurality of loads under normal operating conditions and reversibly interrupting said power for any of said second output channels when current in any of said second output channels exceed limits for said second output channels, and an isolation device and CPU having associated firmware coupled to said second output channels and said external inputs of said second switches via said isolation device.
