See Current Limiting and Foldback Current Limiting.
Function of a power supply that automatically shuts down the supply in the event of reaching a predetermined excessive output current.
An output protection feature that limits the output current of a power supply under overload conditions so it will not be damaged.
A device or system that prevents an electric motor from drawing too much current, overheating, and literally "burning out."
A device operative on excessive current to cause and maintain the interruption or reduction of current flow to the equipment governed.
A circuit breaker or mechanical fuse which opens when the current is greater than that which the equipment has been designed to carry.
A system or device that will shut down a system if an overcurrent exists.
A power supply protection circuit that limits the output current under overload conditions.
A circuit that protects the instrument against excessive current at the input terminals.
Input overload protection is provided in digital instruments to protect the meter from damage whenever voltages in excess of the measuring range are applied to the input. In measuring voltage, the intrinsic high input impedance provides protection in most cases.
Protection of the power supply and associated equipment against excessive output current, including short-circuit current. Protection circuitry is electronic with automatic recovery. Current characteristic is normally foldback type.
