  • Current-measuring arrangement with overload protection
    Patent number: 4700130
    Abstract: A current measuring arrangement including a measuring resistor can be protected against excess currents by means of a PTC-resistor and an amplifier circuit. This protection is self-restoring in contrast to the conventional series-connected safety fuse. The amplifier circuit, the PTC-resistor and the measuring resistor may be arranged so that the property of zero voltage drop of a known circuit arrangement is maintained.
